So....I tried with running all tests of a PharoCore 1.3 and I've got this: cog vm with optimization Time to run all tests:116506
cog vm without optimization Time to run all tests:121930 121930 - 116506 ----> 5424 ((5424 * 100) / 116506) asFloat ---> 4.655554220383499 So...in Cog, running all test, there is an overhead of 4.6% Do we want to pay it ? I would...but I am all ears. Cheers Mariano On Mon, Mar 28, 2011 at 11:08 AM, Camillo Bruni <[email protected]>wrote: > >>> I don't care. I have it working for my "usage".
