Did you try setting unmask irq on on those drives? (-u1 param w/ hdparm) Also u could try setting the nice value of vmware higher so other apps get higher priority (nice -n 16 vmware) and see if that improves the situation. Ofcource IDE is just slow with multi access tasks.. Thats why scsi is still the standard with servers, its designed to be used for multi-app / multi access envirioments. While IDE might have caught up in raw read/write speed, it does not an server architecture make ;-) IDE controllers still lock in these situations, even if different channels are used. Something you could try is to put the vmware ide disk on a different ide controller (promise fasttraq pci cards are quite cheap forinstance, or maybe you could borrow one from someone to test) and see if that helps out. ----- Original Message ----- From: "Jean-Eric Cuendet" <jec@xxxxxxxx> To: <shrike-list@xxxxxxxxxx> Sent: Wednesday, April 23, 2003 16:15 Subject: Machine VERY slow with vmware 4.0 > Hi, > I have a Dell Precision 450 with 2x xeon 2.4GHz.
