Well, here are some results from my 166 Mhz Pentium MMX Toshiba laptop with a Crystal 4232 card.
5: 1 XT-PIC Crystal audio controller
Starting esd (esound-0.2.7-1), and waiting for 60 secs:
5: 32096 XT-PIC Crystal audio controller
Which looks like 530 interrupts/s
I also have a 200 Mhz Pentium MMX with a soundblaster card that gives 590 interrupts/s when running esd. Can it be sampling something at a very high speed? I was however not playing (or recording) anything while these test were done. The system feels about 4 times faster when I kill esd.
