Just in case, are you doing your measurements AFTER the first
generation/compile of the servlet? It's not meaningful to measure taglib
performance before then.

With respect to "caching" evaluation results, it's probably not worth
it, as it would have to do most of the evaluation before it could
determine that nothing has changed, causing a cache read.

Hi all,

We've just started implementing TagLibs in our App and are seeing a 
couple of performance issues which I'd like to check with the group.

We make heavy use of theExpressionEvaluationManger, is there any way to 
tweak this so that it pools/caches results?

We also make a lot of use of the choose/when/otherwise

Can this be a potential bottleneck compared to using a simple "if"
