Looks like somewhere near twice (for small ants), according to other
people.

Yes, you are sharp:-) - the compiling simulator is slower for huge
ants.  Its speed varies from ~1 to ~3 seconds (for 100,000 rounds in a
100x100 world) under the same environment - Mobile Pentium III
1.13GHz, Linux on VMware on Windows 2000.  How about interpreting
simulators?

Anyway, we need the speed for playing all the ants against one
another, for sure!
