30s+ Worker response times

Hi, I have a "simple" fullstack React Router 7 with ssr on all routes. Some routes are limited to do almost no work and the rest is happening client only others have simple CRUD on lightweight data. There is one route that has possibly 500kb-2MB of data but it's not frequency access.

There is also DO with sequential execution due to internal workflow. If users have to wait it's ok but I assume that should not slow any other worker requests.

Lately, I've been seeing 30s+ response time. In most cases, worker will reply. It's almost happening on all API endpoints and even on

. Is there any way how I could profile it or pin point the issue? Logs are showing 10-100ms (which is also horrific for the fact that it returns almost empty ssr page) but then it spends 99.9% somewhere else.
