Would it really matter?  Lua is bytecode, sure it's "slow" but if the 
API exported to it has hooks for things like "read mbufs from socket" as 
opposed to "copyout data" then you can do zero copy without context 
switches.  In addition you get a language that people know as opposed to 
YADSL (yet another domain specific language).
