Ya, that was what I was thinking.

Nice page. Simple, but a good base for study. (just google everything in

there) From reading the HP proliant RT Docs I am guessing most audio work

is not as picky about lowlatency as the stock exchange. They suggest

things that will help but void your warranty.
I found out USB keyboards/mice are bad. Hyperthreading is bad (how do I

turn that off?) How many new MB come with USB as the only keyboard/rodent

input?
It appears that CPU speed control needs to be turned off both in bios as

well as in the OS.
Stay away from allinone CPU/audio/video chips which are SMI hell.
I have to try some of these things...
Anyway, it seems that the big thing with a computer hw upgrade is there

needs to be a lowlatency audit every time. (OS does not matter, this would

be the same for win/OSx)
