[Zope] A Profiler for measuring Zope calculation times ?

Sorry to the list for the first version of my message in HTML format (changed now). Here is my message again: I have been using the Python Profiler from the Zope Control Panel to try to figure ut the bottleneck parts of our site, but I don't really get results I can exploit. It goes too deep in Python for what I need at the moment. What I would need is some indication of the time used to calculate and render specific objects from the ZODB tree. For example the index_html rendering the contents of a specifc folder, or the left_bar_html if there is one called by this index_html. Is there a tool for doing that ? Regards, Kamon eXperts-MD
