[ardour-users] Why am I so slow ?

[derek holzer]

Hi Carl,

some quick recommendations:

1) look up "love sources" in the Gentoo forums, download the latest 
ebuild, build the digest, emerge and compile. [love-sources is 
mm-sources plus a few other goodies]

2) after that, emerge the realtime-lsm module, modprobe it with 
"modprobe any=1" [to test, at least, later you can do it by UID]

3) use fluxbox, ion, ratpoison or another lightweight window manager 
instead of Gnome or KDE while playing and recording

with all this together, you should run glitch free while switching 
desktops and using multiple Jack clients.

good luck,
d.
