A couple of the benchmarks included in ruby-ffi compare ruby-ffi
against DL and a pure ruby method call.

e.g. in the ruby-ffi tree, run:

rake bench:IrV   # single int arg
rake bench:IIIrV # three int args

you can change how many iterations are run by setting the ITER environment var
e.g.
ITER=5000000 rake bench:IrV   # run each test 5 million times
