I like to suggest my "ZopeProfiler" product to analyse such things

It is unable to safely measure time spent in C functions
(such as "tree[id]= object") and will associate their time
with the enclosing Python function. Nevertheless,
you can clearly notice when the time is spent in another
Python function (such as "manage_afterAdd").
