Thanks for the tip, I tried it and if the red lines are any
indication, it seems that atop thinks my disks (md raid 1) are the
problem being busy over 60~70% of the time. However that is sort of
expected since most of the expected activity on the server is
smtp/pop3.

Unfortunately, I did not know about atop previously and don't have a
baseline to compare against :(
