Introduction

MemoryProfiler provides memory profiling support for Zope. It use heapy (http://guppy-pe.sourceforge.net/#Heapy) in internal. It’s just an interface to this tool.

• You start profiling by a click to the start button, you take an snapshot of the memory at instant t.

• Each snapshot is store (as string) results to be consult later (link to the date).

• The button clear db cache clear all zeo cache of all mounting point so you can see the impact of the memory of those cache.

• You can see reference of a particular class in memory with the button reference detail.

For windows users, you must compile guppy. There is an egg for python 2.6 but no for python 2.4. I have fatal error with Mingw to compile guppy. I hope that we have soon a binary egg to for python 2.4.

I hope that this tool give to us usefull informations to the memory consume by zope.
