Comment 27 for bug 488354

Some values for a modified speed test, using 10000000 iterations (10 times less) over AddMixedFloats instead of AddTwoInts:

original code:
 direct took 10.72 seconds
 invoke took 17.41 seconds
 So, invoke overhead was ~ 6.69 seconds (~ 38%)

with attachment 433119:
 direct took 10.79 seconds
 invoke took 16.69 seconds
 So, invoke overhead was ~ 5.90 seconds (~ 35%)

with the WIP patch:
 direct took 10.78 seconds
 invoke took 14.58 seconds
 So, invoke overhead was ~ 3.80 seconds (~ 26%)
