Yowza. If I were seeing that kind of memory change in just one project
I'd say there was a bug and the code was just dying. :-)
What sort of configuration were you using in each case? A 512 KB Drupal
process seems, um, low, especially compared to the other projects listed
there. (Drupal 7 is normally rather memory hungry.)

Hi,
I've just rerun some synthetic and real-life benchmarks.
All the test were run on the same box (Linux, Core2 Duo 3GHz, 4GB RAM).
5.3 and 5.4 where configured and build with the same options and ran as
FastCGI server with the same number of processes and set of extensions.
