DOS also gives the fastest possible performance, since you own the
cpu and don't have to give up cpu cycles for multitasking. That's
the reason I mentioned it - the response while sifting through a
megabyte of data was practically instantaneous from the keyboard,
but it would be a bit slower in Windows.

Don't you have gaps where the various interrupts take control away?
Perhaps your application doesn't have this problem, but if the gaps
occur at "critical times" - say, in the middle of a single-shot
acquisition - this would seem to be a problem. Do you turn off
interrupts, and if so for how long? Are there any significant
penalties for turning them off for an "extended period"?
