This is an interesting question... It would be really nice to see some performance numbers comparing JSP vs. Velocity. I've googled around a bit, but didn't find any good comparisions. My guess is that Velocity is faster, but perhaps not 'that' fast as it used to be. Newer JSP-implementations are actually pretty snappy. We're building an application on Oracle 9iAS (Oracle Containers for Java, and Oracle JSP) - and it renders pages *really* fast (way under 100ms under heavy load). The JSP code is ugly - no taglibs - but after some testing we're moving to more taglibs now. //Anders -- |===================================| | Anders Engström | | [EMAIL PROTECTED] | | http://www.gnejs.net | |===================================| |Your mind is like an umbrella. | |It doesn't work unless you open it.| | /Frank Zappa | |===================================|
