Slow busy server

[Andrew Shitov]

Hi,

During the last few days I experience problems with slow loading of
the Act sites (mainly ye2013, of course, but others as well) and slow
ssh connection. I looked at the top output and it says "load averages:
18.60, 18.18, 18.80" and lists the number of postgres processes with
big CPU usage numbers.

Is it something to look at in sense of system administration?

  PID USERNAME     THR PRI NICE   SIZE    RES STATE  C   TIME   WCPU COMMAND
