I have a test system, where I need to execute hundreds of commands using
Jython. After switching from 2.2 to 2.5, I noticed that the test run
took almost three times as long as previously (~1h vs. 2h50min). Since
even previously most of that time has been spent on interpreter startup
(With Python2.5, the tests run in ~6 min), I investigated this a bit
further. I ran this on my console:

$ time for i in `seq 20`; do jython -c 'import sys; print sys.path'; done

With 2.2, the result was:
real	0m33.868s
user	0m39.526s
sys	0m2.216s

With 2.5, however:
real	1m40.181s
user	2m14.572s
sys	0m4.924s

Almost three times slower here as well.

Here's the interpreter version:
