Package: collective.profiler
Introductioncollective.profiler is a tool that helps developers to analyze code performance.
It patch code via an zcml declaration.
It use the very goodprofilehookspackage in internal. collective.profiler is just an interface to this toolThere is two directives :timecall-> give you the number of seconds by callsExample<configure

  <profiler:timecall

       method="listFilteredActionsFor"
         />
 </configure>give you some information about the call of listFilteredActionsFor methodWhen you start in fg your zopeinstance you can see after the startlistFilteredActionsFor (.../eggs/Plone-3.3.5-py2.4.egg/Products/CMFPlone/ActionsTool.py:94):
   1 calls, 0.238 seconds (0.238 seconds per call)profile-> print the results of profilingExemple<configure
