WordPress Migration: Keep .htaccess by Choosing LiteSpeed Over Nginx

September 26, 2026
WordPress Migration: Keep .htaccess by Choosing LiteSpeed Over Nginx

For WordPress and WooCommerce sites, LiteSpeed usually wins on caching efficiency and dynamic-page speed thanks to LSCache and Apache compatibility. For static sites, reverse-proxy setups, or high-concurrency APIs, Nginx remains the stronger pick because of its lean event-driven model and native proxy_pass handling. Test both under your actual traffic pattern before committing, since the gap narrows once caching is configured well.

TL;DR:

  • LiteSpeed generally provides faster dynamic page speeds for WordPress and WooCommerce sites due to its built-in LSCache engine and native Apache .htaccess support.
  • Nginx excels with static content, reverse proxying, and high-concurrency API workloads because of its event-driven architecture and flexible configuration options.
  • Benchmarking shows both servers perform similarly in static throughput, with LiteSpeed gaining an edge in cache-heavy PHP dynamic pages when properly configured.
  • Migration from Apache is simpler with LiteSpeed due to its compatibility with existing .htaccess and httpd.conf files, whereas Nginx requires rewriting rules manually.
  • Small performance gains from server choice matter most for high-traffic sites, while most WordPress and WooCommerce sites benefit more from optimal caching and configuration than from raw speed differences.

LiteSpeed vs Nginx at a Glance

Both servers use event-driven architecture, which is why they both beat older, thread-per-connection designs like Apache's prefork model under heavy load. Past that, they solve different problems.

  • License model: Nginx open-source is free and unrestricted; LiteSpeed ships as free OpenLiteSpeed or paid LiteSpeed Enterprise with domain, worker, and RAM tiers.
  • Best for: LiteSpeed suits WordPress/WooCommerce and Apache migrations; Nginx suits reverse proxying, static content, and API traffic.
  • Native caching: LiteSpeed includes a built-in page cache engine (LSCache) at the server level; Nginx relies on proxy_cache or fastcgi_cache modules you configure yourself.
  • .htaccess support: LiteSpeed reads Apache's .htaccess and httpd.conf natively; Nginx uses its own config syntax with no .htaccess support at all.
  • PHP integration: LiteSpeed uses its own LSAPI; Nginx pairs with PHP-FPM over FastCGI.
  • HTTP/3 support: Both support HTTP/3 and QUIC, though LiteSpeed rolled it into stable releases earlier than most Nginx deployments outside Nginx Plus.

The .htaccess gap is the one that trips people up most. If your site runs on a decade of accumulated Apache rewrite rules, that single row of the comparison can decide the whole migration.

What Do Benchmarks Actually Show?

Independent testing tends to show Nginx and OpenLiteSpeed trading the lead depending on workload, with LiteSpeed pulling ahead specifically on cached WordPress and WooCommerce pages. A widely cited comparison across Apache, Nginx, LiteSpeed, and OpenLiteSpeed found Nginx and OpenLiteSpeed both among the top overall performers for raw static throughput, while LiteSpeed's advantage showed up most clearly once its cache engine handled dynamic PHP requests.

Benchmark reality check: Practitioner discussions on ServerFault note that LiteSpeed, OpenLiteSpeed, and Nginx often land within a few percentage points of each other under equivalent tuning. The deciding factor is rarely the server binary itself. It's cache hit ratio, PHP opcode caching, and how much work each request forces the backend to do.

For static file serving, requests per second and time to first byte (TTFB) barely separate the two once you're past a few thousand concurrent connections; both handle that load without breaking a sweat. The real divergence shows up in dynamic workloads: a database-driven WooCommerce checkout page, a logged-in WordPress dashboard, or an API endpoint hitting a database on every call. Here, cache configuration and PHP process management matter more than the server's raw connection-handling speed.

Watch three metrics when comparing, not just requests per second:

TTFB under load. A server that serves static assets fast but stalls on PHP execution will still feel slow to visitors. Measure TTFB specifically on your slowest dynamic pages, not your homepage.

Sustained throughput versus burst throughput. A short benchmark run can flatter a server that struggles once caches fill and connections pile up over an hour of real traffic.

CPU and RAM under concurrent PHP execution. This is where LiteSpeed's LSAPI integration and Nginx's PHP-FPM pool tuning produce genuinely different resource curves, covered in more detail below.

Common benchmark pitfalls to avoid on your own tests: running synthetic load from a single geographic location, testing only cold-cache requests, ignoring database load entirely, and comparing default configs instead of tuned ones.

How Does LSCache Compare to Nginx Caching Setups?

LSCache and Nginx's proxy-based caching solve the same problem from opposite directions: one is built into the server, the other is bolted on through configuration.

The LiteSpeed Cache plugin for WordPress is free and does the configuration work, but the actual caching happens at the server level. The plugin itself is an interface. Its own documentation is explicit that the page-caching features only activate on a LiteSpeed server; install it on Nginx or Apache and you keep image optimization and minification, but lose the server-side cache engine entirely.

Nginx takes the opposite path. You configure proxy_cache or fastcgi_cache directly in the server block, defining cache zones, keys, and expiration rules yourself. Nginx's ngx_http_proxy_module handles this well and gives you fine control, but every rule is something you or your host has to write and maintain.

The practical differences show up in daily operation:

  • Purge behavior: LSCache auto-purges specific pages when WordPress content changes; Nginx cache purging typically needs a module or manual cache key management.
  • Fragment caching (ESI): LiteSpeed supports Edge Side Includes, letting you cache a whole page while excluding a cart widget or personalized block; Nginx has no native ESI equivalent.
  • Storage format: LSCache stores compressed cache entries automatically; Nginx cache storage depends entirely on how you configure proxy_cache_path.

This is why managed WordPress hosts increasingly pre-install LiteSpeed with LSCache configured out of the box. It removes a genuine configuration burden, particularly the purge logic that trips up self-managed Nginx setups on busy WooCommerce stores. For more on how the plugin and server pieces fit together, see what LSCache actually does under the hood.

Pro Tip: If you're moving a WooCommerce store to LiteSpeed, enable ESI for the cart and mini-cart widgets first. That single setting often fixes the "cached page shows stale cart count" bug that trips up new LSCache users.

Why Does LiteSpeed Handle Dynamic Pages Differently?

Both servers use an event-driven model, handling thousands of connections without spinning up a thread per request. Where they split is how each one talks to PHP.

LiteSpeed uses its own LiteSpeed API (LSAPI) to communicate with PHP processes. Nginx has no built-in PHP handling at all and instead forwards requests to PHP-FPM over FastCGI, a separate process pool that Nginx proxies traffic to. That extra hop, Nginx to FastCGI to PHP-FPM and back, is where LiteSpeed's architecture claims an edge: LSAPI's tighter integration reduces that additional proxy step, which can shave measurable time off TTFB on database-heavy pages.

LSAPI and FastCGI request flow comparison

In practice, that saved hop matters most on sites doing a lot of small, dynamic requests: admin-ajax calls, logged-in dashboards, API endpoints hit repeatedly.

The operational trade-offs follow directly from this. PHP-FPM under Nginx gives you granular pool tuning: separate pools per site, custom process limits, and detailed status pages that most sysadmins already know how to read. LSAPI configuration lives inside LiteSpeed's own admin console and is arguably simpler to set up correctly out of the box, but it's a smaller ecosystem if you need to debug something unusual. Either way, monitor the same core numbers: PHP process count under load, memory per worker, and queue wait time when concurrent requests exceed available workers. Undersized PHP-FPM pools or LSAPI worker limits will bottleneck a fast server just as easily as slow code will.

How Hard Is It to Migrate from Apache or Nginx?

Migration effort depends almost entirely on how much of your stack leans on Apache-specific configuration.

LiteSpeed is built to be Apache-compatible, reading existing .htaccess files and httpd.conf directives without a rewrite. If your site has years of accumulated redirect rules, security headers, and plugin-injected .htaccess entries, LiteSpeed can often adopt them directly. Nginx uses its own configuration syntax entirely, meaning every Apache rewrite rule has to be manually translated.

Before switching either direction, work through this sequence:

  1. Audit your .htaccess file and list every custom rule, redirect, and security directive it contains.
  2. Check plugin compatibility, since some WordPress security and caching plugins write Apache-specific rules that need Nginx equivalents.
  3. Build a staging environment on the target server and replicate your full configuration there first.
  4. Load-test the staging site under a realistic traffic simulation before touching production DNS.
  5. Swap traffic during low-traffic hours, keeping the old server live and ready to roll back.
  6. Monitor error logs and TTFB closely for the first 48 hours, since misconfigured rewrite rules often surface as 404s or redirect loops.

Skipping the staging step is the single most common cause of migration headaches, particularly with complex WooCommerce rewrite rules.

What Does Each Server Cost to Run?

Nginx's open-source edition costs nothing and carries no domain or worker limits. LiteSpeed splits into two tracks: OpenLiteSpeed is free and open-source with no artificial limits, while LiteSpeed Enterprise is a paid license tiered by domain count, worker processes, and available RAM.

That licensing structure directly shapes where you'll find each server. Shared hosting plans typically bundle LiteSpeed Enterprise licenses the host has already paid for, since the per-domain cost gets absorbed across many customers. VPS and dedicated server owners face a real decision: pay for a LiteSpeed Enterprise license tier that matches their resources, or run the free OpenLiteSpeed edition, which approximates Enterprise performance in many workloads but skips some proprietary enterprise integrations.

Nginx Plus, the commercial add-on with support and extra load-balancing features, mainly makes sense for large-scale API infrastructure and enterprise reverse-proxy deployments, not typical WordPress hosting. According to W3Techs, Nginx runs a significant share of websites with known server data, noticeably more than LiteSpeed. That gap reflects Nginx's dominance in general web infrastructure and reverse-proxy roles, not a performance verdict for WordPress specifically, where LiteSpeed's managed-hosting presence is much heavier than the overall number suggests.

How Do You Choose the Right Server for Your Site?

Match the server to what your site actually does, not to which one benchmarks slightly better in isolation.

  • Running WordPress or WooCommerce? LiteSpeed with LSCache usually wins on cached page speed and purge handling, especially if you're migrating from Apache and want to keep existing .htaccess rules.
  • Serving mostly static content or acting as a reverse proxy? Nginx's lean event loop and native proxy_pass handling are hard to beat for SSL termination and load balancing in front of application servers.
  • Building a high-concurrency API? Nginx's maturity as a reverse proxy, paired with a well-tuned caching layer, tends to handle sustained connection volume with a smaller resource footprint than a full application server stack.

Before deciding, run three concrete tests: simulate your actual traffic mix (cached versus dynamic requests) rather than a generic load test, measure real-user TTFB with a monitoring tool rather than relying on synthetic benchmarks alone, and check your cache hit ratio under that simulated load, since a low hit ratio makes the server choice almost irrelevant.

If you're evaluating a host or an internal team's setup, ask directly: which server and PHP handler do they run, do they pre-configure LSCache or Nginx caching, and can they show cache hit ratios from existing customer sites. For a deeper look at how these choices ripple into overall site speed, see this breakdown of hosting's impact on performance.

Pro Tip: Don't trust a host's advertised "powered by LiteSpeed" badge alone. Ask whether LSCache is pre-configured and auto-purging, because a LiteSpeed server with caching turned off performs no better than plain Nginx.

What inSave Hosting Brings to This Comparison

Some hosting providers run WordPress and shared plans on LiteSpeed with LSCache, PHP8, MariaDB, and free CDN integration built in, enabling the caching behavior described above without manual configuration. Free migration and staging tools cover the Apache-compatibility advantage discussed earlier, letting sites move over with existing .htaccess rules intact rather than rewritten from scratch.

A few practical notes worth flagging for anyone tuning this stack directly: cache purge rules need testing after any plugin update, since a misconfigured exclusion list is the most common cause of stale cart pages on WooCommerce. Staging environments catch most rewrite-rule conflicts before they hit production, which is worth the extra ten minutes every time. For more on the underlying technology, see this guide to LiteSpeed for developers and this overview of how advanced hosting tech affects performance.

When Does a Small Performance Edge Actually Matter?

A few percentage points of TTFB rarely justifies a migration on its own. Migration risk, staff familiarity, and plugin compatibility usually outweigh marginal speed gains for small and mid-size sites. The calculation flips for high-traffic stores or API platforms, where even a small per-request improvement compounds across millions of calls. For most WordPress sites, a properly configured cache on either server beats an unconfigured "faster" one every time. Stability wins more often than benchmark charts suggest.

FAQ

What's Better Than Nginx?

Nothing beats Nginx outright. It depends on the job: LiteSpeed often outperforms it on cached WordPress and WooCommerce pages thanks to LSCache and LSAPI, while Nginx remains stronger for reverse-proxy work and static-heavy or API traffic. inSave Hosting runs LiteSpeed on its WordPress hosting plans specifically because that workload favors it.

Does LiteSpeed Replace Apache?

LiteSpeed can serve as a drop-in replacement for Apache since it's built to read the same .htaccess and httpd.conf files without rewriting them. It doesn't run Apache underneath; it's a separate, event-driven server designed for Apache compatibility rather than a wrapper around it.

Does Netflix Use Nginx?

Netflix has publicly discussed using Nginx as part of its content delivery infrastructure for handling high-concurrency connections at scale. That reflects Nginx's core strength as a reverse proxy and load balancer, the same capability that makes it a common choice for API-heavy platforms rather than typical WordPress hosting.

Is LiteSpeed Free?

It depends on the edition. OpenLiteSpeed is free and open-source with no domain or worker limits, while LiteSpeed Enterprise is a paid license tiered by domain count and resource limits. Many hosts, including inSave Hosting's shared hosting plans, include an Enterprise license as part of the plan cost.
