Checklist Comparison
Choosing a web server is a trade-off between performance, operational complexity, and (sometimes) licensing. This page gives you a practical comparison matrix and a checklist you can use to validate what is actually running and whether the core pieces (PHP handler, caching, TLS) are configured correctly.
For many WordPress sites, OpenLiteSpeed is a strong free default. For WooCommerce sites that benefit from fragment caching (ESI), LiteSpeed Enterprise is often worth considering. Nginx is an excellent choice when you need reverse proxy capabilities and you can invest time in configuration.
The Engine Evaluation Matrix
| Technical Vector | Apache | Nginx | OpenLiteSpeed (OLS) | LiteSpeed Enterprise (LSE) |
|---|---|---|---|---|
| Underlying Architecture | Process-heavy | Event-driven loop | Event-driven loop | Event-driven loop |
| .htaccess Parsing | Supported | Not supported | Supported | Supported |
| Primary PHP Link | mod_php / PHP-FPM | PHP-FPM (Manual routing) | LSAPI | LSAPI |
| Caching Integration | Extremely weak (Thick Plugins) | FastCGI Cache (Hardcode) | LSCache Native | LSCache Native + ESI |
| High Concurrency Stability | Lower by default | High | High | High |
| Ideal Target Topology | Obsolete legacy cPanel blocks | Strict static domains, Reverse Proxy routing | Typical publishing grids | Massive WooCommerce logic |
| Financial Overhead | Completely Free | Completely Free | Completely Free | vCPU Registered Licenses |
Engine Validation Diagnostics
Use these commands to identify which engine is running on the host.
# Execute a comprehensive scan locating any operating web services
ps aux | egrep 'apache|nginx|lshttpd'
# Force specific binary checks natively
apache2 -v
nginx -v
lshttpd -v
Master Go-Live Initialization Checklist
Following the physical installation of any web server, explicitly guarantee all required sub-systems function cleanly before migrating active domain DNS topologies natively.
- Execute baseline version checks: Avoid unsupported/obsolete engine versions.
- Confirm PHP handler: Nginx ->
php-fpm; Apache -> prefermpm_eventwith PHP-FPM; LiteSpeed ->LSAPI. - Enable caching layer: Verify FastCGI cache or LSCache is working (example:
x-litespeed-cache: hit). - Compression: Ensure gzip/brotli (where applicable) is enabled for text assets.
- Protocol transport: Enable HTTP/2 and (if used) HTTP/3/QUIC.
- TLS: Verify certificates and disable legacy TLS versions.
Explicit Deployment Reminders
- Avoid over-provisioning: Use LiteSpeed Enterprise when you need an Enterprise-only feature (like ESI) or vendor support.
- Prioritize the bottleneck: For WooCommerce, focus on stable behavior for cart/checkout (cache exclusions, object cache, DB performance) before chasing micro-tuning.
- Keep rewrites manageable: Very large
.htaccessfiles can add overhead on every request. - Pair with a CDN where appropriate: A CDN can reduce global latency and origin load regardless of the origin engine.
