How slow is slow? Is it slower than in Go and Python? Why would 
unwinding 8 stack frames be so slow? Is it a language mandated 
speed issue or just a runtime issue that could be fixed with a 
compiler switch?

Most of the time is spent waiting for async request from 
memcaches/databases and other types of network traffic so you 
usually have some free cycles on a decent CPU. With native code 
and lightweight threads (coroutines) you should be able to handle 
100+ concurrent requests per process.
