run top and paste the output the top portion of the screen.

I would suspect it is IO wait. You can get into disk contention if you have multiple containers fighting for disk. You will notice the IO queue is building up and that is shows you are waiting for IO transactions.

See the field labeled WA, that is wait time. Basically time you are waiting for IO to complete.

If that is high, you can increase the cache used by Linux BUT if the system crash you are at risk of losing saves.
