Hi Folks,<br>
<br>
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.<br>
<br>
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:<br>
24% SmallInteger>>negative; 22% SmallInteger>>bitShift: (I don't use bitShift: explicitly) and 20% Array>> collect:<br>
<br>
Which image and VM should I use to verify this before sending the complete message tallies?<br>
<br>
Cheers<br>
<br>
Herbert<br>

I used the following recent image / vm:<br>
