Jep, Jython and CPython compared, all in a nice little script
So, in relation to the work with Jep ( http://www.nidelven-it.no/weblogs/hosting/blog_entry?id=1368... ) - I've been building a script that can build and setup Jep, Jython and CPython in a directory, and then have a compare.sh script that runs the same code on the 3 different systems.The installation script is here:
https://raw.github.com/morphex/PythonCompare/master/install....
Here's the output from the generated compare.sh file:

As you can see, the Jep and CPython scripts are fairly stable in terms of execution speed while Jython varies a bit but gets faster (probably due to the HotSpot technology). If you want to change the test to something else, you can try "./jdk1.7.0_21/bin/java -jar usr/lib/jython-standalone-2.5.3.jar -m compileall -l ." and mytest.py will be recompiled, along with the other .py files.
Now, feel free to use the install.py script as you like, I think it's a good example of how to setup the whole thing in a specific directory.. there was some hair-pulling to get the entire build process setup so that linking and dependencies were setup the right way.
Fun to work with a mix if Python, Java and Bash scripting for a change. I think being able to use Python to script for example prototypes or even production code is a big win in terms of productivity.. weak typing has its place in rapid application development. :)
