Hi,

This morning, I updated my Cuis-Smalltalk-dev working directory. A new 
VM was fetched along a few additional changesets to Cuis.

I fired up the installation of my DrGeo IDE against this latest Cuis..

I tested DrGeo under this new setup, it works fine but I observed  a 
sub-nominal graphic rendering speed. At least a 50% slowdown compare to 
a DrGeo build against Cuis 7.3#7158.

I observe this slow down in DrGeo window but not with other window as 
the browser. So may be VectorGraphics related...

I then cross run my DrGeo builds and VMs. The result is interesting.

The DrGeo with latest Cuis image and executed with the former VM (at 
Cuis7.3#7158) is even slower!

When I executed the DrGeo build with Cuis7.3#7158 with the newer VM, it 
is even slower, the slower of all.

I am confused.

Here is the build image to test it

Thanks
