Joel Richard resolved SLING-4532.
---------------------------------
Resolution: Invalid
Closing because the overhead is added in a BindingsValuesProvider which is
called in DefaultSlingScript.verifySlingBindings and not in DefaultSlingScript
itself.
> 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
> Labels: performance
> 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.
