RE: [cobalt-users] high CPU load (idle CPU) ???

["Adam Knowles" <adam@xxxxxxxxxxxxxxx>]

Hi,

After reading this msg I ran 'top' on my Raq4i. The Mem overview shows:

4:52pm  up 4 days,  7:07,  1 user,  load average: 0.09, 0.07, 0.01
74 processes: 73 sleeping, 1 running, 0 zombie, 0 stopped
CPU states:  0.1% user,  1.1% system,  0.0% nice, 98.6% idle
Mem:   127860K av,  123460K used,    4400K free,   61752K shrd,    2668K
buff
Swap:  131532K av,   25392K used,  106140K free                   16820K
cached

I'm currently using up about 9gb/month in bandwidth. Would any of the
above worry an experienced sysadmin (which I'm not!) ?  Should I put
more memory in?

.. speaking of which, what would be a good book(s) to get on how to do
medium->advanced stuff with Raq's from the shell?

Ta v.much all.
