Hello Sebastian,
thanks for you replay.

in my server, actually, there are many many users.
this overload problem manifests itself especially in the morning.
What should I do? I have already given more ram, 4GB (server is 32
bit) and multiple cores.

logs, apache I noticed that there are also several ip of foreign
countries and not only in my country.

You could give me some guidance on what to check?
