[Hosting PERFORMANCE] TTFB ~7s + FastCGI timeout (idle timeout 160 sec) near PHP execution limit

Hello!

I'm experiencing significant slowness (TTFB ~7s on the WP back‑office, even without plugins) on my PERFORMANCE hosting (designq.cluster030.hosting.ovh.net / designbymathieu.com / PHP 8.3).

I see a recurring FastCGI timeout in the error logs: AH10141: FastCGI: ... idle timeout (160 sec).

This 160 s idle timeout seems too close to my PHP execution limit (165 s), which causes 500 errors under load.

Does anyone have an idea what is causing this FastCGI bottleneck, or know how to adjust/bypass this timeout on the server side on shared hosting?

Thanks in advance!
