Sure, but this thread's all dealing with speeding up ruby generally, 
not hand-optimizations that the app programmer can do to speed up a 
specific part. If you really wanted speed, it wouldn't be too 
surprising to see a speedup of 100x to 200x by just completely 
recoding in C or Fortran. (But, then, that'd be... painful in many 
cases :)
