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

> The commit applied in [r1629144|https://svn.apache.org/viewvc?view=revision&revision=r1629144] seems to have affected the JSP scripting engine performance.
> The Sightly JSP [performance tests|https://github.com/apache/sling/blob/trunk/bundles/scripting/sightly/testing-content/src/main/resources/SLING-INF/apps/sightlyperf/test/test.jsp] show a 5x degradation on my machine when compared to running the same tests on {{org.apache.sling.scripting.jsp}} 2.1.4.
