You may want to drill down the timing differences using:

MessageTally spyOn: [ .... ]
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.
