Yeah, that's my biggest gripe with the "GC'd language are as fast as native" crowd. You end up doing all sorts of contortions in order to get the allocation/cache coherency that you need that you're better off using a language that has proper support for it. I love scripting languages for orchestrating logic(luaJIT!) but when you need to massively vectorize your data so that you get full utilization of the prefetcher there really is no substitute.
