Hi Dann,

No special techniques.  Java simply isn't as slow as most folks think.  I use
IBM's VM which is excellent (50% faster than Sun's).  I've toyed with the idea
of a C++ rewrite, but I don't think I would get more than a 1.5-2x speedup.

Actually, this reminds me that I've been meaning to look at some of the native
compilers that are now available for Java.  Maybe I can find out if my 1.5-2x
estimate is correct.
