hi,
i have a 2.8 Dual Xeon with 2 GB of ram and 2 SCSI drives
OS
Redhat 3.0Ent with cpanel latest stable
kernel
Linux xxxx.xxxxx.com 2.4.21-15.0.4.ELsmp #1 SMP Sat Jul 31 01:25:25 EDT 2004 i686 i686 i386 GNU/Linux

now should i have hyperthreading enabled or disabled ?
why i am asking ?
because i moved from a P4 3.0 with 1.5 GB of ram server which had hyperthreading enabled and SCSI drive and had an ok load
now on this monster server i am faceing high load even after optimizing mysql and install mmcache

any idears ?

Our dual Xeons boot slower than our single processor boxes. Seems normal.
