Subject Re: Jasper performance

As Glenn mentioned, Jasper is in the process of getting a rework.  But in the
mean time and since you mentioned taglibs, you may want to look at the tag
pooling module that was added to tc 3.3.  If your jsps use a lot of tags,
you should see a big performance gain.  Let me know if you have questions
about tag pooling.

I was hoping to add tag pooling to tc 4, but have been very busy.  So unless
I gain some spare time, you'll probably need to wait until the new Jasper
is available (at least for tag pooling).
