I am running basic performance tests on document creation factory

Here is the famous point :

How many wrote expressions and doing what ? Why do you suspect them to
be responsible for that ?
Write expression are stored in CPSFields subclasses (CPSStringField,
CPSListField...)
"I think write expression evaluations are evaluated by
Datamodel.py". I
don't know yet what to alter to disable the write-expression
contained
in portal_schemas/my_schema/myField:write-expression
Which file should I alter to disable write expression calculus ?
Can somebody point me toward relevant links ?
Field.py : processValueBeforeWrite()
If I were you, I'd use ZopeProfiler for this (google it)
it's easy to filter results to know how much time is spent in this
method since you've got its name now :)
Besides, you can analyze your perf problem way outside of write
exprs, of course
