Zope Profiler (1.6)

Unlike with the standard Zope profiling support, Zope runs normally in multi-threaded mode. Statistics gathering can be enabled/disabled dynamically via the ZopeProfiler object in the Control_Panel. This objects supports most features of Python's pstats.Stats timing analysis class and is much smarter than the standard Zope profiler. Should the features be insufficient, then statistics data can be saved to files and later analysed with Python's Stats class.

The product installs itself via "monkey patching". It overrides ZServer.PubCore.ZServerPublisher.publish_module. Since version 0.2, it carefully tries to coexist with other applications that override the same resource (WingIDE's Zope debugging support is one such application). There is no guarantee, however, that it succeeds.
