In general I thought it would be good to focus on Linux because that's
where the interesting real-time patches are, and because it's possible
to do apples-to-apples comparisons between Linux versions.
Win2k seems to be a decent OS for soft real-time. It's preemptible so
in many circumstances it'll do better than vanilla Linux (before 2.5, at
least) for scheduling latency purposes. Certainly Win NT / 2k / XP are
miles ahead of the Win 3.1 / 95 / 98 / Me family.
If you're interested, there are some real-time experiments that I did on
Win2k here:
