-----------------------------------

             Summary: Performance: DefaultSlingScript has too much overhead
                 Key: SLING-4532
                 URL: https://issues.apache.org/jira/browse/SLING-4532
             Project: Sling
          Issue Type: Improvement
          Components: Scripting
    Affects Versions: Scripting Core 2.0.28
            Reporter: Joel Richard
         Attachments: measure.patch

While I was profiling a slow page, I saw that a significant amount of time is spent inside DefaultSlingScript. Since profilers often cannot be trusted, I added some code (see attachment) to measure the time spent without the script execution itself (JSP in my case) and came to 8% of the whole page rendering time. Since the JSP itself has been compiled before the measurements, I would have expected the overhead clearly below 1%.

The page which I profiled has about 100 sling includes.
