collective.profiler : un outil pour analyser votre code

Il y a deux directives :

• timecall -> Pour tracer le temps de vos fonctions

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>

Quand vous démarrez votre instance en mode fg vous devez voir à chaque appel de fonction les lignes suivantes

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 -> outil fin d'analyse de code

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>

Quand vous démarrez votre instance en mode fg vous pouvez voir à chaque appel de fonction les lignes suivantes
