The 200 times difference comes from my own comparison of the same domain model implemented idiomatically in both ColdFusion/ColdSpring/Transfer and Java/Spring/Hibernate. Similar experiments conducted by colleagues give similar results. Mark Drew did some testing with a totally different scenario, but the results are in the same ballpark. Not sure why you'd find this surprising. Java code to solve a given problem isn't remotely similar to the bytecode that CF spits out for the same problem, unless that problem happens to be interpreting a dynamic language. The fact that they are both "Java" is far less significant than the fact that one is dynamic and the other static. There have been similar results from comparisons of Jruby and Java, and Groovy and Java. We're not talking about 20% or 50% performance differences, we're talking about orders of magnitude.
