hi steve,

i believe this to be incorrect.

true, mochiweb comes loaded with many nice functionalities: json,  
cookies, multipart, ... fact is, these are not called on every  
request, but are *available* to a programmer upon need: an incoming  
request get does *not* get though all this code unless it is  
specifically asked by a programmer.

misultin speed compared with mochiweb comes from the different  
approach to the socket handling, and that alone. as you can see, the  
benchmark used is very simple, it just echoes a variable passed in  
GET, and the code to do so is very similar for both libraries.

if you are referring to joe's bench i'm pretty familiar with it :)
