jayqhacker <[email protected]> added the comment: My hardware has apparently changed (Xeon E5620 @ 2.4 GHz, 12 MB cache; still Red Hat 5.8 64-bit), but 2.0 unfortunately brings no improvements for this case. For reasons mysterious to me, the relative gap between CPython and pypy is considerably widened, to almost 2X. (Note CPython and pypy 1.9 and 2.0 are compiled from source with gcc 4.1.2; 1.8 is the binary from pypy.org.)
I'm also throwing in Jython just for giggles. Running on Oracle JDK 1.7.0_21, performance and memory usage vary wildly with choice of heap options, but -J-Xmx4G -J-XX:+UseConcMarkSweepGC seem to give the best results.
