I first tested some sites on BerqWP's URL tester on their homepage and their predicted improvements were already too good to be true, so I got a free plan to test with and the plugin did even better.

Bought Tier 6 and have installed it on at least 10 sites already with amazing results. Tried WP Rocket, Flying Press, W3 Total Cache Pro, Litespeed Cache, Super Page Cache, Perfmatters, NitroPack, Seraphinite Accelerator, Autoptimize, Asset CleanUp Page Speed Booster PRO and more.... yes I have tried them all.

Not sure what kind of AI scientific wizardry BerqWP is using, but it easily beats all the above performance enhancers out of the box. Only NitroPack comes close, but NitroPack gets expensive for larger sites with lots of pages. Only setup changes made were changing to Aggressive Mode and Enabling free Cloudflare account integration. BerqWP includes a speedy CDN (digitalocean) and integration with free Cloudflare accounts to enable Cloudflare's Edge Caching. Cloudflare Pro accounts are compatible, but not Enterprise or Cloudways Cloudflare Enterprise add-on. This is because BerqWP needs to control the entire page caching process which means no other page caching can be in use or you'll get a "Cache is disabled" warning.

Every site I have installed this on had incredible GTMetrix and Google Page Speed Insights (PSI) scores. By incredible, I mean 98-100 mobile and 99-100 desktop on almost every site I installed it on (no sites were <92). Now if BerqWP could also fix my accessibility scores the same way!

As a fairly new product, sure it has a few things that could be better like real time caching progress status (currently need to refresh page constantly), large sites with 500+ pages can take a while to build the cache fully. Options are slim as they aren't needed, you'll save hours per site fiddling and tweaking a dizzying array of settings like in Litespeed Cache or WP Rocket only to get minimal gains after all that work.

Try BerqWP for yourself, guaranteed you'll be buying more tiers!
