What can be with the Apache server?

Question

Apache HTTP Server

In general, the problem is very frequent, I googled enough, I can not find a solution.
it turns out that apache slows down when I reboot everything works but after a minute everything hangs again
8GB Ram 80GB SSD Disk Ubuntu Ubuntu 14.04 x64 Intel(R) Xeon(R) CPU E5-2630L v2 @ 2.40GHz, 4 cores
I can’t figure out what’s wrong.
when the site slows down in the logs, nothing terrible happens.
there was a suspicion of a ddos ​​attack, but it was excluded because
ps aux | grep apache | wc -l
gives only 15 or 20
I don't think that because of 20 processes the site can slow down
logs iptraf data collection during braking 1 hour
no suspicious IP

Help me to understand?

Answer 2

You have tons of mistakes, start with them

Answer 3

Has anything been updated/done on this server?
Are there any logs of how the server/machine worked before?
Both nginx and apache work for you. Something tells me that the car is a mess.
