Resin used to be faster than Tomcat 3.x, but with TC 5.0? I somehow doubt it is that much faster anymore, but I haven't seen any numbers lately.
As to the high traffic site. Soon, I'm working on it, 600 million PI/month enough? OK, it won't solely be velocity based, just to allow the customer to exchange little snippets inside the portal framework using their own templates. I am however fortunate enough to use a CMS system with excellent caching and not to have to generate fully personalized pages. Load tests are pending in our project, I do expect a degradation in performance, that is obvious. Velocity just isn't compiled code. I don't expect it to be a problem though, there is that cache :) As far as caching is concerned, one can always look into using a caching framework like oscache (opensymphony.org) on top of everything. Velocity itself just caches the parsed AST trees (which is good, I would hate to have to reparse the templates all the time). That and good design are probably all you need.
