[Libjit] libjit about 1000 times slower than native functions

[Omkar Wagh]

Hi
I was just profiling the basic tutorial mul_add and it turns out that 
libjit is about 1000x slower than native function calls for the mul_add 
tutorial.
Profiling with callgrind suggests that most of the time is spent in :-

jit_apply (17.5%)
jit_apply_builder_add_arguments(14.25%)
jit_type_normalize (9%)
jit_thread_get_control (6.5%)
jit_type_get_param (5%)

And so on...

So my basic question is, am I missing something here? Does libjit work 
well for small examples or is this some constant cost that will always 
be added for any kind of libjit compiled function and it's only when the 
compiled functions get "large enough" will libjit be worth it?
