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) -- Len Ovens www.OvenWerks.net _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
