Code Speedup Experiments

This is a log of the speed up experiments that we are conducting.

Here are some experiments we could conduct. For each, we would compare against a pure Python implementation: Fib hand optimized to Java, no frames or other call setup support as seen in PyBaseCode.

• Fib pure Python, but with indy.

• Nested loops. Array multiplication?

• Guard failure of a loop, call into interpreter (PyBytecode) with well-known offset and synthesized frame. (Limited CPS.)

• Etc

Related Speedups

Before venturing into these experiments, I tried to speedup the PyByteCode. You can view the page on that at CodeSpeedupExperiments/PyByteCode

Repository

All the work is being done at a mercurial repo at http://bitbucket.org/shashank/jython-experiments/
