Quoting my answer to M-Station

This is really hard to say. First I must admit that ecasound
performance is not optimal. I'm interested in high-level programming
and design methods, and ecasound has always been my test bench
for new ideas. I prefer simple solutions and try to avoid unnecessary
hacks. The resulting code is easy to maintain and more stable.
But back to your question, with my P166 box I can mix about 14-16
mono tracks in realtime. But I'd say that no machine is too slow or
too fast for ecasound. If you don't have enough hardware resources,
you can do separate submixes (like bouncing with analog 4-tracks),
apply effects separately (to free cpu-power), or if nothing else
helps, you can do everything non-realtime.

... so ecasound is quite flexible when it comes to hw requirements.
