[linux-audio-user] hello gentoo? speed up please...

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



hello all - got a question - I've only recently been stopping and taking a
look at my studio computer's performance and in the almost year since I
change from Red Hat 9 to gentoo, it's been more solid on some things, but I
notice a huge latency difference - ie: I have to run Jack at -p 8192 to get
anything done in Ardour

Anybody have any tips on what to look at to tweak it?  Seems like it should
do better than that... I didn't see it as a problem until in the last few
days I started playing with playing softsynths live directly into Ardour -
you've gotta be running at -p 1024 or there's a latency that screws up your
playing - at 8192 it's a downright 8th note delay...

Here's some vitals that I can think of:

OS:  gentoo 2.6.6-rc1 kernel (alsa built in)
jack: 0.99.0
ardour: beta28
jack command line:

jackd -R -d alsa -d hw:0 -r 48000 -p 8192 <------- (or whatever)

harddrive:
multicount on
io support: 32 bit
unmaskirq on
use dma on
keepsettings off
readonly off
readahead on

chip:  2ghz amd (I THINK - not at computer now)
ram:  512MB


thanks for any ideas! :)
