The real advantages Velocity has are:
- firmer separation of logic from presentation
- template language that UI designers and web authors can use safely and
learn quickly
- no time consuming compilation step
- macros!
- usable scoping on included content (this is a huge advantage on a
full-featured webapp)
Traditional JSP with or without taglibs are a pretty raw deal. They
don't perform particularly well, implementing caching is a heroic feat,
they crap up the internalized string pool, and they're hard to write and
easy to break. Taglibs really don't solve much, and can't be maintained
by non-developers anyway.
I converted a fairly busy internally used webapp, has maybe 20-30
concurrent users on a teeny machine. I haven't even turned off
development mode yet and there really hasn't been any noticeable change
in performance. It's a LOT easier to maintain now and since the UI guys
can just dive right in their and get dirty, it's starting to look
*fantastic*. A huge improvement over the HTML 1.0 widgets "look and
feel" I had going, chuckle...
Sorry no hard numbers, but, there are other advantages than raw speed
which usually matter more.

Hello all,
Has anybody got a chance to compare Velocity with traditional JSP? In terms
of performance? Any tradeoff out there? Thanks a lot for your input. Thx.
