Introduction
collective.profiler is a tool that helps developers to analyze code performance. It patch code via an zcml declaration.
There is two directive :
- timecall -> give you the number of seconds by calls
Example
<configure
xmlns="http://namespaces.zope.org/zope" xmlns:profiler="http://namespaces.plone.org/profiler" xmlns:five="http://namespaces.zope.org/five" xmlns:i18n="http://namespaces.zope.org/i18n"> <profiler:timecall class="Products.CMFPlone.ActionsTool.ActionsTool" method="listFilteredActionsFor" /> </configure>
give you some information about the call of listFilteredActionsFor method
When you start in fg your zopeinstance you can see after the start
listFilteredActionsFor (.../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 profiling
Exemple
<configure
xmlns="http://namespaces.zope.org/zope" xmlns:profiler="http://namespaces.plone.org/profiler" xmlns:five="http://namespaces.zope.org/five" xmlns:i18n="http://namespaces.zope.org/i18n"> <profiler:profile class="Products.CMFPlone.ActionsTool.ActionsTool" method="listFilteredActionsFor" /> </configure>
When you start in fg your zopeinstance you can see after the start

Options
timecall
- immediate : If you want just a summary at program termination, use False
profile
- skip : If skip is > 0, first skip calls to fn will not be profiled.
- filename : If filename is specified, the profile stats will be stored in the named file. You can analyse it with profiler tool or pstats.Stats(filename).
- If immediate is False, profiling results will be printed to
sys.stdout on program termination.
- If dirs is False only the name of the file will be printed.
Otherwise the full path is used.
- sort can be a list of sort keys (defaulting to ['cumulative',
'time', 'calls']). The following ones are recognized:
'calls' -- call count 'cumulative' -- cumulative time 'file' -- file name 'line' -- line number 'module' -- file name 'name' -- function name 'nfl' -- name/file/line 'pcalls' -- call count 'stdname' -- standard name 'time' -- internal time
- entries limits the output to the first N entries.
