Hello All,
I am new to plesk and managing a VPS. so do not fully understand how resources are shared amount websites.
We have a VPS (8 core 32gb) with few subscriptions. One subscription (say A) has 2-3 websites (much higher data processing requirement, databases around 1.8GB ) under it and other subscription (say B) has about one website with 12-15 subdomains (lighter data processing and storage requirement, smaller databases 100-400mb).
Initially when after VPS was setup only A was there and websites under it were performing really well. but as we added B and so many subdomains there (although having lighter load) performance dropped for A (more than 60-70% for longer operations).
As of stats CPU usage never goes above 25%, plenty of free ram , data usage very rarely touches 70% usually within 10-20% lower. Yet performance has dropped for all.
I was hoping plesk could handle this issue through setting limits to CPU, RAM and DISK.
So now after installing Cgroups component I have set subsc B to have 30% cpu limit, disk to 100mb/s.
But still there is no performance improvement for subscription A.
Is because of number of files or something else?
Any suggestions are welcome !
