> In general you'd be right, but this is not a benchmark of code running in those languages. There is no loop, no heavy computation - it's just returning the headers. That should take less than 1ms in either language.

They can't have it both ways... Fastly was the one that complained that their JS engine still wasn't up to par (being in beta), so clearly the language of choice (or interpreter/compiler/whatever) DOES matter.

Either the language doesn't matter (in which case, replicate the JS test) or it does, in which case this isn't even a useful comparison.
