I think tag pooling was dropped for 5. (I can't remember) Benchmarks never showed a measureable performance increase. See the archives for tomcat-dev possible disscusions.

John,

I have noticed in the generated java files that tags that are java
classes seem to get pooled ok, but tag file (jsp tags) do not seem to
get pooled at all.. Has anyone else seen this and if so is it by design.


I assume you mean instances of JSP tag libraries being used in JSP files.

The specification contains methods to setup and re-set tag objects so that they can be pooled and/or reused. It occurs to me that I've looked at the generated Java source code from a JSP for Tomcat 4.1.x, and the instances are not pooled.

I was actually a little disappointed because the Tomcat guys are generally pretty clever, and I'd think that someone would get a huge hard-on after get this working (I know I would).

Does anyone know about Tomcat 5? I'd love to actually contribute to the project, but I haven't looked at line 1 of code from any of the releases (okay, so I hacked DataSourceRealm to add some logging when I was pissed off, but I don't know anything about how the JSP engine works).
