I offered VPS and with virgin Debian it often hangs: simple ssh command responds too long. It is bad :(
I made benchmark for it: every 2 minutes it starts ffmpeg to convert 30 seconds low quality video. Normally it takes 3 seconds, but in hang time about 20 seconds.
Also i pinged VPS every 2 minutes. Graph is same.
Another server from this hoster
Same situation, but don't critical
How to avoid this situation?
Seems, that neigbour VPS, hosted on same dedicated server periodically starts high CPU loading task. Maybe it is system backup or same task. As i know memory is guaranteed, but not CPU.
Also i have another VPS from this hoster, and it seems ok(it also have same peaks but far less)
Dedicated server is too expensive to this project.
This is hoster independed situation, changing provides is bad idea
