hi, julien. i use linuxsampler but with the qsampler gui, so i did a
test using qps to get the stats.
my box is also 2.8 ghz but i have 1.5G of ram.
at idle linuxsampler ( not including gui ) uses 1% cpu maximum.
if i bang up and down on as many keys as i can with both forearms cpu
use reaches 22%.
memory use obviously depends on the size of the loaded soundfont.
if i load the biggest font i have - maestro grand piano v2 - memory use
is 187M, again not including gui.
with 512M of ram and no X running this should not stress your system.
are you using a really big soundfont?
is ecasound using a lot of ram at idle?
