--------------------------------------------
Sure Nathan, I am still refining the fix and running it through JProfiler. I
will update this issue with the patch and before/after output as soon as I can.
Thanks

> Key: VELOCITY-815
> URL: https://issues.apache.org/jira/browse/VELOCITY-815
> Project: Velocity
> Issue Type: Bug
> Components: Engine
> Affects Versions: 1.7.x, 2.x
> Reporter: Oswaldo Hernandez
> Labels: perfomance
>
> When MapGetExecutor is instantiated by the UberspectImpl it iterates through
> all the interfaces implemented by the object's Class to figure out whether
> it's a java.util.Map
> This could be replaced by an instance of test on the object received by the
> Uberspect which would be much faster. We noticed this as a hotspot after
> upgrading to 1.6 through our Performance Tests JProfiler output.
> I am happy to provide a patch for this, it would be nice to get this on the
> maintenance branch as well if possible, so that we don't have to maintain a
> fork until we upgrade.
