Check to see if your VM has ZipPlugin (Smalltalk listBuiltinModules).
Good point. I see it. Doru, do you ?
This has a big effect on Monticello performance.

Hi,
I looked a bit into the slowness of the OS X Jenkins Cog VM with
Monticello. The problem exists and it is reproducible.
I performed the following experiments using the following script:
Time millisecondsToRun: [ 1 to: 100 do: [:x | | window | window := MCWorkingCopyBrowser new show. window delete ] ]
I ran it on the same image using the following vms (on Mac OS X Lion): - Jenkins VM from 31.08.2011 - Cog VM r2489
I ran the scenario twice with two different setups:
1. I placed the image in an empty folder:
Cog VM 2389: 4808 ms Jenkins VM: 7345 ms
2. I places the image in a folder that already had a large package-cache
with 7400 mcz files:
Cog VM: 4867 ms Jenkins VM: 50754 ms
So: - even if there is no package cache, the Jenkins VM seems to perform 1.5 times slower - when there is a package-cache, it becomes hardly unusable.

I did not forget about this, but I did not have enough time yet.

Hi,
Since a couple of weeks I am working with the Cog VM built on
Jenkins:
https://ci.lille.inria.fr/pharo/view/Cog/job/Cog-Mac-Cocoa/
Here is a little feedback. It worked quite well, the only problem is that Monticello is really slow in the Moose image. This means that even opening the Monticello Browser takes several seconds.
I thought that this might be induced by something in the Moose image, but if I try with the Elliot's VM (2489), it works blazingly fast.
Thanks for the information, Tudor. Apparently the difference between Eliot's VM and Cog-Mac-Cocoa that they are using different frameworks (Carbon vs Cocoa) and i don't know too much details about the difference there. John or Esteban may have better insights how to fix that.
Cheers, Doru
