I’m having trouble with
High Time to First Byte (TTFB) on my Wix Studio site. PageSpeed Insights shows 2.5s TTFB on mobile (“poor” range, threshold is 1.8s), and LCP is affected too (2.8s). INP and CLS are both fine, so it’s specifically a server response time issue.

Live site (Basic plan)

What I’m trying to do
Bring TTFB consistently under 1.8s. My main concern is crawl budget, I get a lot of AI/search bot traffic and slow server response can throttle crawl rate.
What I’ve tried so far
- Compressed all images heavily (Squoosh)
- Removed almost all third-party apps/widgets
- Checked my 301 redirects (recent URL restructure), all clean single-hop, no chains
- Read a thread here confirming Elite plan mainly improves CMS/database performance, not general page load, so not convinced a plan upgrade alone fixes this
Extra context
One page’s HTML response is around 2MB, which seems unusually large and might be a factor. Curious if dynamic/CMS-driven pages vs. static pages make a measurable TTFB difference, or if there’s anything else within Wix’s control that actually moves the needle.
