I have no idea. I haven't seen any conclusive benchmarks comparing CFMX to JSP. I'd take issue with his statement that Java is a "high-performance language" to some degree, I think, anyway, but it's largely irrelevant to my argument. In a "real" application, you're not going to see the performance differences he's touting. Take a look at your debug output for your own applications; where do you think you're likely to see the most time consumed? In my experience, this has been database interaction. Do you expect queries to run ten times faster from JSP? Now, on the other hand, let's say you write an application that does lots of math, or lots of string manipulation stuff. Well, that stuff may well run faster in JSP - maybe even ten times faster. But that's not what's in most web applications, and in general, that stuff usually doesn't belong in the presentation layer of a web application anyway. In a well-architected J2EE web application, you probably wouldn't do most of that in JSP, either - you'd write a Java class and invoke it. You can easily do the same from CF, largely negating the speed difference in the one place where it may be significant.
