You would not have to do anything. All small methods that do not contain 
complex stuff like loops or exception handling would be inlined. Instant 
factor 4 speed boost :-)

General guidelines on what you have to do to increase the chances of 
things being inlined can be found here (under "method inlining")

This is for the current microsoft JIT, but I guess that similar rules 
apply for mono.
