[PlanetCCRMA] XFCE works best for me!

I was messing around trying to get low latency working, removed nearly
every service, and switched to using xfce and that reduced memory
requirements plus it seems even hdparm -tT hard disk tests run faster in
xfce than in gnome.
Now I get 1.33 ms latency at 48khz quite solidly as long as I am not
using the hd (which is slow on my machine even though I used tuning
params, I think LVM has something to do with it, disk druid set up
2*60gb drives as one LVM volume) cat /proc/ide/via shows hard disks as
88.8mb/s (thats ide capability I suspect as barracuda drives are specced
40mb/s) but hdparm -tT tests show average about 38mb/s in xfce and only
30mb/s in gnome.
it seems under ccrma many apps require the gnome/kde libs installed, is
it possible to compile progs that dont need the gnome daemons like
bonobo, gconfd etc. that will work under xfce i.e. is GTK tied to Gnome
daemons etc. or are there compile options?
As an interesting note I thought I had fixed the problem my modifying
the HAL config according to this article, which is useful as far as
external drives and laptops are concerned

This changes hald from a

Also It seems the memory management method and paging can also cause
problems (only 512mb ram on my pc), I reckon for speed you need no LVM
and separate devices for swap file and program files/general data and
another one for audio data. I now know what I need to do for FC4
anyway.... A faster graphics card might help as well...
