This sounds similar to the PID benchmarks that we sometimes run. The
number varies quite a bit based on the board and drivers being used.
Using NI-DAQ, great for buffers, but not the fastest for single point
I/O, you can achieve about 1500 Hertz in a PID loop with a good
processor. The intelligent DAQ board is a 486 and does a little above
1kHz, but with much greater determinism and less jitter. Faster HW or
quicker access to the HW is the key. Without I/O, the PID should do
above 100kHz (this is just a guess based on numbers several years ago on
a slower machine).
Using buffered I/O where processing isn't required on individual points,
both LV and DAQ can run much much faster.
