Honest question, does performance really matter all that much for a web framework? Internet latencies should be in single digit to low double digit milliseconds range. I would expect the slowest of web frameworks in bash to parse and route an http request in 1ms, so even if you replaced that with a hand written custom assembly version running at 1nanosecond, that would still be dwarfed by the networking jitter.
