Well but look at your bi and bo, and then the wa column. So looks like you=
have some IO Wait which probably means it's waiting on disk activity to ge=
t things done, and lots of writing to disk. Have you looked at adding a ra=
mdisk for your checkresults, status.dat, and temp_file? That should help e=
liminate most of the heavy disk i/o from the nagios perspective. Since it =
doesn't look like you are swapping memory you should be able to throw some =
at a ramdisk. You can probably start with 64MB and watch it, might have to=
go higher depending on your workload.

Hi, Daniel,

As we can see below, I think it is not a hardware problem. The idle CPU is =
beteween 60 and 80 %, very good.

Thank you very much.
