of the Xeons. We have a Dell server with 2 Xeons that show the same
result. You say in your follow-up email that you have disabled
hyperthreading in the BIOS - why?</FONT></SPAN></DIV>

busy. It will be available for applications if required. BTW, if you
have 2GB of RAM I believe it's best to have 2-4Gb swap
space.</FONT></SPAN></DIV>

<DIV>Hi Gurus,</DIV>
<DIV> </DIV>
<DIV>I just built an ibm x345 with 2GB ram and 2xCPU(xeon) running Linux ES
3.0 with kernel - Linux version 2.4.21-9.0.1.ELsmp. Apps running are
httpd(stock), sendmail and bind. </DIV>
<DIV>This is not yet launched on production so basically this machine is idle.
I ran /usr/bin/top and it gives me these output (sorry for the display):</DIV>

<DIV>My concern is how come it shows 4 cpu's and the memory used way the
total. Does that mean when I go to production this machine will need more
memory?</DIV>
<DIV> </DIV>
<DIV>Is there some settings/tuning parameter I should be aware of?</DIV>
<DIV><BR>Thanks for any info.</DIV>
