NGINX vs Apache for WordPress — which actually wins?

If you've read more than two WordPress speed articles, you've seen the claim that NGINX is faster than Apache. That's broadly true, but the more useful question is when it matters, by how much, and whether you should care. The short answer is that for almost every modern WordPress site, NGINX or LiteSpeed beats Apache — but the gains come from how the whole stack is configured, not from the web server alone.

NGINX wins on concurrency. Its event-driven architecture handles thousands of simultaneous connections with a small memory footprint. Apache's traditional prefork model spawns a process per connection and runs out of RAM far sooner. On a 1GB VPS, NGINX comfortably serves 1000 concurrent requests where Apache starts swapping at 200. For sites that get traffic spikes — news mentions, paid ads, viral social posts — that headroom matters.

Apache wins on familiarity and flexibility. The .htaccess file lets users override server configuration without root access, which is essential for shared hosting at scale. That's why every budget host still defaults to Apache: it's not faster, it's easier to support. cPanel, Plesk and most one-click installers assume Apache. If you're moving from shared hosting, you're almost certainly moving from Apache, and you'll need someone to translate your .htaccess rules into NGINX config.

Then there's LiteSpeed — the third option most articles skip. LiteSpeed is a commercial web server that's typically faster than NGINX for WordPress specifically, because it has deep integration with the LiteSpeed Cache plugin (including ESI for cached fragments with dynamic content), efficient PHP handling via LSAPI, and built-in HTTP/3 and QUIC. OpenLiteSpeed is the free version. For pure WordPress or WooCommerce hosting we often recommend it over both NGINX and Apache.

Our recommendation is rarely the web server in isolation. It's the whole stack: web server, PHP version and handler, OPcache settings, MySQL/MariaDB tuning, page cache (FastCGI, LSCache or Varnish), object cache (Redis), CDN in front. Get that right and the NGINX-vs-Apache question becomes a footnote. Get it wrong and no web server will save you.
