ZopeProfiler supports the collection and analysis of timing profiles.
Such profiles tell you about expensive parts of your application
and can give valuable hints towards optimization.
The new version allows the profile analysis to be restricted
to the functions matched by a regular expression. You
can immediately determine the statistics, callers and callees
of interesting functions (without the need to browse through
hundreds of statistics records).
This new version was very helpful in the determination
that Zope (from version 2.8 on) misses an important ZODB optimization
causing several times more ZODB storage loads than expected (and necessary).
