Nice work. However, the VM (Interpreter or Cog) is independent of the
image (Squeak / Cuis / Pharo). To get comparable results you should run
either image on both VMs (or, since you just care about performance,
use Cog for all three).

Thanks Bert. I only used the All-In-One-Click packages and am not
familiar with how mix & match VMs and images. It is not something
I have looked
<br>
into yet and a pointer to to some information on that would be useful.
Also, Cog seemed to be only newly arrived for Squeak and I didn't want
to hit
<br>
complications. I was hoping it was fair to compare Squeak-Plain with
Pharo-Plain and them to Pharo-Cog.
<br>
<br>
To a comment on the morphic-flavour-performance post I have attached a
graph of Levente's results for CogVM with recent images.

Thanks. I was too lazy to convert from the output to the format used by
the spreadsheet.

I notice a big difference in your results between Pharo and Squeak that
may be related to an enlightening comment left by <cite class="fn">Henrik
on the morphic-flavour-performance article<br>
> T</cite>he intersects check used for culling really dislikes
floating point bounding box though, as it has to convert them to
Fractions before comparing with integers.<br>
<br>
Would you feel inclined to rerun your tests using "rounded" ?<br>
OR... if you could direct me to instructions on how to update my images
from the one-clicks to the versions you used, then I will re-run on my
hardware to get a direct comparison to my previous results. I've been
googling terms like "squeak updating to trunk" but there is a lot of
fluff that isn't what I need.<br>
