Yep, that was my best-case. However, that was on either a fractal
terrain generator or a fake Towers of Hanoi. Both are 100% integer
operations. No strings, *very* minimal database references, no floating
point, no communication. Just integer cranking. That type of stuff shows
the *most* slowdown from native code. MUD code that does a lot of
database references and string operations will show much less difference
between native code and byte-code (or any other reasonably efficient
interpretation scheme.)

In a previous post, I was saying much the same as JC is saying above.
A couple of months ago, I recall posting some results indicating that
my server on this 300Mhz Pentium-II looked to be able to handle around
500 users **ignoring network communication**. It is the communication
that I think is the real cost.
