pip install Products.PTProfiler==1.5



PTProfiler is a small profiling system for page templates in Zope 2. It times each TAL expression and lists the results in a table ranked by processing time.

Using PTProfiler

Do mind that this product (when enabled, see below) requires some extra processing time for page templates, so isn't recommended for production sites.

To enable and view the results, place a PTProfiler Viewer object somewhere in the Zope tree, and press the Enable button. After some page templates are viewed, you will see a list of paths to each of those page templates (or, in the rare case the path isn't known, the id). When you click one of the items, you will see a list of all the expression calls in the template, ordered by total time spent on that expression.
