Grails vs Rails Performance Benchmarking Intro Recently someone asked the question: "Where are the Grails vs Rails benchmarks??". Since we actually haven't got round to optimising Grails I thought it was silly that we should benchmark a 0.4.2 release against Rails which is now at 1.2.x. Nevertheless, to allay concerns about Grails I decided we should do it anyway. This page represents the results.
