ZopeProfiler allows you to profile your Zope requests and analyse the resulting runtime profiles in various ways (timing statistics, callers, callees). Profiling can provide a high degree of insight into the expensive parts of your application and be used as base for runtime optimizations. ZopeProfiler 1.7.1 is a bugfix release. It fixes a bug with regular expressions containing '<' or '&'. It also replaces the function name based output filtering introduced in 1.7 with 'pstats' stdname based filtering. This filtering is more flexible (although a bit more difficult to use) and leverages better the 'pstats' infrastructure. More importantly, entries selected by a regular expression are now sorted as specified. This allows you to quickly determine the most expensive selected functions.
