It's the step size you want your simulation to advance - nothing more
and nothing less (and it's measured in the time units you're using -
which may be seconds or may be not).

If your simulation should look realtime to someone who is sitting at the
computer - then step size should be the amount of time elapsed from the
last update (not only in this thread).

You may also try running at fixed stepsize (saves a lot of headache in
some situations), and adjusting your rendering accordingly.
