Okay, this has to be the worst report of all time, but one of my ligher
loaded servers feels more sluggish then the heavy loaded one ... starting
commands seems to 'hang' for a bit and then go, changing folders in mail
takes forever, etc ... yet there is about a 1/4 the processes running on
this system ... so this is more a 'is there something I shuld be looking
at' kinda email, since I can't pinpoint anything as being wrong, it just
*feels* sluggish :(

The server itself is a Dual PIII 1.2Ghz on an Intel MB in an Intel SR2300
chassis ... Adaptec 2120S ZCR RAID Controller ... 4GB of RAM ... 6x36GB
Seagate Cheetah drives in a RAID5 configuration ... Onboard Intel ethernet
...

But, I can't seem to find anything to back up the feeling ... so don't
even know what I'm asking on this one ... the server has been up 12hrs (I
rebooted earlier to give Scott some info he requested from the boot):

Does anything look off here?

As a comparison, my loaded server looks like (after 2days, 4hrs up):
