Hi Chris

You might want to take a look at the TclBench test code inside the 
tcljava/tests
directory. I used that to create the following comparison of C Tcl to 
TJC compiled Jacl:

The main thing is to make sure hotspot has warmed up and compiled your code
before getting runtime numbers to compare. If you just grab some time 
via the time
command, the results will be misleading unless hotspot has compiled the 
code. Also,
make sure you use many thousands of iterations with the time command. If 
you need
some more focused help with this project, I am available on a consulting 
basis for
whatever optimization assistance you might need.
