Ken Restivo a ?crit :
This is an EEE 1000 (the dmiinfo.txt file on my site shows model/serial num). It has a
1.6Ghz 32-bit Atom processor. This seems more than up for the task of running the
softsynths and DSP that I absolutely require.
My small ecasound daemon which has all my LADSPA plugings (CAPS amp, TAP autopanner, etc)
for my Rhodes sucks up 50% CPU according to top. But everything plays. Even AMS works, no
runs, glitches, or errors.
The crappy hda-intel card works fine. Video updates are noticeably slower, but I don't
care; I use it mostly headless. I could also plug in my USB M-Audio FastTrack and use that
too, but I haven't needed to yet.
For simple/cheap practice or casual gigs, this works. For the bigger gigs, or for
recording/editing work I will probably continue to use my full-size, heavy/bulky, 64-bit
Core 2 Duo 2.33Ghz laptop.
But I may do a few optimizations on the EEE still: later JACK version, use the FastTrack,
recompile kernel for 1000HZ timer, etc.
Let me know what kind of CPU usage reports you-all'd like, and what tools you
recommend for calculating/determining usage.

I'm happy to report that I am writing this
from my new EEE softsynth, running an RT-patched kernel, jackd, and several softsynths.
System info, if anyone is interested, is here:

happy to know that. what EEE model is it?
I have an EEE also (700 family), without an RT kernel, but with rtprio
capabilities set in limits.conf for jackd. The main issue to me is that,
as i extensively use the audio INPUT, i get a lot of periodic audible
overrrun with ALSA for INPUT audio with the in-board soundcard. This is
not a cpu usage issue, though.
What surprised me was that using jackd over OSS layer did work for audio
input, without audible overrun. I wonder why then, using the ALSA api
does not work as well.
The only solution i have for ALSA currently is to use an external usb
cheap interface.
So, i may compile an RT kernel to see if that fixes my issues.
