You may want to drill down the timing differences using:
MessageTally spyOn: [ .... ]
or
TimeProfileBrowser spyOn: [ ... ]
This will give you detailed breakup of time spent in message sends and the
memory stress.
Squeak and Pharo images are much bigger than Cuis so they may take up a larger
portion of the memory resulting in frequent calls to GC. If you notice a
difference in GC calls, you may want to repeat the trials with larger memory
for the larger images.
