Initially, we were skeptical—especially our IT team. However, after testing on our staging environment (since our site handles six-figure traffic and has numerous plugins), there were no crashes or interruptions. This gave us the confidence to move forward with transferring to the live site.
Within 24 hours, the mobile performance score skyrocketed from 75 to 98, and the desktop score jumped from 94 to an impressive 100 (!). I’m already giving this a solid 5 tacos because it’s truly amazing. Even better, there were no errors with other plugins. Now, we’ll just need to wait 28 days to see how the "origin" Core Web Vitals of the site hold up.
After these days I can decide definetly, how the improvement is.

IT DID NOT TAKE 28 DAYS - we may have to revert
We took a big leap of faith moving our six‑figure‑traffic site live with BerqWP. After flawless staging tests, our scores shot from Mobile 75 → 98 and Desktop 94 → 100 within 24 hours—so we gave it 5 tacos without hesitation.

But two weeks in, everything except the homepage cratered. Over 100 pages are crawling, despite the promised 28‑day uplift that never came. We’ve flagged this as URGENT, shared full access, and yet support trickles back: three days for the first reply, then long silences, and no real fixes.

Frankly, we’re disappointed. If this isn’t resolved immediately, we’ll have no choice but to revert to our old setup. BerqWP might dazzle on a single landing page, but for a larger site, it’s falling flat.
