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. -ken _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
