How Can I Reduce My WordPress Site’s Server Response Time (TTFB)?

Emily Routledge · May 1, 2025

I’m running WordPress on shared hosting and struggling to bring Time To First Byte (TTFB) below 300 ms. Which specific server-level configurations (e.g. switching PHP versions, tweaking OPcache settings, adjusting MySQL parameters) or host-side optimizations (like LiteSpeed, Redis, etc.) have you applied that made a real difference?

Thanks for any concrete examples or config snippets!

For large sites like woocomerce sites, Redis cache helps a lot but usually not available on standard shared hosting accounts. Having quality hosting, good servers and network is going to be very important as well, because you can tweak and tune the services all you want, but the quality of the server resources and network will be a limit there.

Switching to PHP 8.1+, enabling OPcache with higher memory (opcache.memory_consumption=256), using LiteSpeed with LSCache, and enabling Redis object cache significantly improved my TTFB. Also, optimizing MySQL with query_cache_size=64M and reducing autoloaded options helped a lot.

If host its running litespeed webserver, install litespeed cache plugin proferably before any other technique, PHP 8.1 as minimum, also no matter what you do on your site, if you have panel account for example you will never be in control of how much ram/cpu cores its assigned to your account so take this in mind also. Another tip its just to add your site under cloudflare DNS and hace CDN cache.
