[tcljava-dev] Performance results for new TJC compiler

[Mo D. <md...@un...>]

Hello all

I have made the claim that the new TJC compiler for Jacl will improve runtime
performance, but until now I have been lacking real numbers to back up that
claim. I have now imported the tclbench framework into the tcljava/tests/tclbench
directory in CVS and modified the module so that it can be used to test Jacl.
This tclbench module will test just the execution time for a command, it ignores
shell startup and shutdown time and will take the hotspot compiler into account.

Proper benchmarking can be very tricky, but I think the following results
will stand the test of time.

These results compare Jacl 1.3.2 vs the current CVS version of Jacl with TJC
compiled commands.
