pybench focuses on runtime performance, not memory usage. It's way of creating and deleting objects is also highly non-standard when compared to typical use of Python in real life applications. It's also rather difficult to benchmark memory allocation, since most implementations work with some sort of pre-allocation, buffer pools or free lists. If you want to use a similar approach as pybench does, ie. benchmark small parts of the interpreter instead of generating some grand total, then you'd probably have to do this by spawning a separate process per test. > refs: > > http://code.google.com/p/google-highly-open-participation-psf/issues/detail?id=105&colspec=ID%20Status%20Summary > > http://evanjones.ca/memoryallocator/ > > http://www.advogato.org/person/wingo/diary/225.html -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Source (#1, Nov 29 2007) >>> Python/Zope Consulting and Support ... http://www.egenix.com/ >>> mxODBC.Zope.Database.Adapter ... http://zope.egenix.com/ >>> mxODBC, mxDateTime, mxTextTools ... http://python.egenix.com/ ________________________________________________________________________ :::: Try mxODBC.Zope.DA for Windows,Linux,Solaris,MacOSX for free ! :::: eGenix.com Software, Skills and Services GmbH Pastor-Loeh-Str.48 D-40764 Langenfeld, Germany.
