TwitterHi there,
I host an online forum using Plesk. Since I migrated to a new server I'm running into a severe problem: All client requests get immediate responses from the server, except a few that take around 18-23 seconds. So the users either get an instant or a super slow response. It's not due to the forum software, since the problem occurs all over the place and I can't nail it down to specific routes (I use sentry.io to monitor performance). Neither the CPU (80% idle) nor the ram (>90gb free) are fully occupied. So I think it's a hosting problem.
The website is served via Nginx and PHP-FPM. So far I tried:
- different Nginx .conf settings (worker_processes, worker_connections)
- different PHP-FPM settings (static, on-demand)
I'm at a point where I don't know where to go from here. This problem seems to occur like every 20-30th request or something around that. Super weird.
Please, if anyone has any idea what's going on here, I'd appreciate your help.
