Hi Folks,

I'm doing some simulation in Squeak 3.8 and as some tests ran over two 
minutes I decided to try a more recent image with cog vm.

To my surprise 4.4 took around 5 times as long as 3.8. I believe I do 
nothing out of the ordinary here. Time is spent in:
24% SmallInteger>>negative; 22% SmallInteger>>bitShift: (I don't use 
bitShift: explicitly) and 20% Array>> collect:

Which image and VM should I use to verify this before sending the 
complete message tallies?

Cheers

Herbert

I used the following recent image / vm:
