The best behavior, IMHO, is to be able to select what speed to run at. UAE,
a very good Amiga emulator, lets you choose which processor to emulate and
at what speed, including a setting that runs the emulator as fast as
possible. Granted the architecture of the Amiga is a bit more sensitive to
CPU timings than most computers, due to it's tightly integrated video and
sound processors, so CPU speed selection might be more important than, say,
in an S/360 emulator. It would still be very useful, however, being able to
select accurate speed emulation or being able to "overclock" your virtual
mainframe.

It is the best behaviour? I've seen a couple of
emulators which
regulate speed, because it is sometimes necessary for games and
frequently necessary for demos. An additional advantage is that it
reduces the rate at which electricity is converted into heat (ie. it
uses less of the host machine's CPU), so my batteries last longer and
my hands are less toasty. :) And I think it is fair to say that an
emulator which runs at two or three times the original machine's speed
will usually be fast enough. (If speed was really *that* important
you wouldn't be using an emulator.)
