Well, I think there are two cases of JSP you need to evaluate:
-JSP with pure scriptlets
-JSP with JSP tags
scriptlets will probably be almost as fast, I'm guessing. Tags could be much
slower, since the way that containers handle tags is different for each
container.
The main thing to remember is that with velocity, printing out the foo bean
property is just $foo, which is almost a direct map to vs.find("foo"). But
in JSP you have to do <ww:property value="foo"/> which requires the
container to handle the tag properly, then execute the tag code, and then
finally make the vs.find("foo") call. I think it's that extra work that must
be done (when using JSP tags in WW) that causes such a large overhead.
These are just thoughts at 11:46PM, please take them with a grain of salt :)
