T4.1.5 possible ognl cache problem

[denis queffeulou <de...@air2web.com>]

Hi all,

I'm making some profiling on an web app made with Tapestry 4.1.5 which 
returns XML.
The result are disappointing as the average access time (got with 
JMeter) is around 2000ms.

In JProfiler, I found that OGNL expressions compilation uses 40% of 
processing time.
As the JMeter script is requesting always the same page on the webapp, 
I'm wondering why the expressions are always compiled. The cache seems 
not to be used:

31896 invocations on ExpressionCache.getCompiledExpression
31140 invocations on Ognl.compileExpression

Is there someone to give me a clue to have better performances ?

Thanks
