I just performed some benchmark of pymalloc, compared to glibc 2.2 malloc, using xmlproc (a pure-Python XML parser) as the sample application. On an artificial input document, the standard configuration ran 16.3s; the configuration with pymalloc ran 15s.

I've also been playing with this on FreeBSD and OS/2, using PyBench and others, with gains of about 3%.

I recommend to enable pymalloc by default; I can commit the necessary changes if desired.

+1

Also interesting to note that current CVS seems to be doing ~7-8% better than 2.2 even without pymalloc, at least on those benchmarks I've compared both with (pystone, PyBench.
