> Key: SLING-3635
> URL: https://issues.apache.org/jira/browse/SLING-3635
> Project: Sling
> Issue Type: Improvement
> Components: Scripting
> Affects Versions: Scripting JavaScript 2.0.12
> Reporter: Marius-Andrei Danila

>
> The Rhino Javascript engine allows you to choose the level of optimization
> for the generated byte code or it lets you select whether the scripts should
> be run in interpreted mode [0].
> Currently, there is no way to configure this. By default, Rhino compiles
> scripts into JVM classes using the optimization level 0.
> This option should be configurable, and the default value for this
> configuration should be "-1" - meaning run scripts in interpreted mode. Since
> we are not caching script compilation artifacts, the interpreted mode gives
> the best performance for short-running scripts.
> The attached patch implements this improvement by exposing a configuration
> entry in the Rhino Javascript engine factory component.
