Thanks for the help. I would speak to TMD hosting because I do have a dedicated server.
We are not sure how much RAM does your server have, but this website has configured 1GB only, maybe you can change for a bigger value in cPanel (We didn't try to).
Also it would be a good idea to enable all cores and add swap. Even if they say you don't need it, it is always a good thing to have it just in case.
Please let us know if you need further help on anything else.
