Sorry, yes of course, not a pharo 1.4 vm. The VM info fro mSystemReporter:

Yes, the same ( a copy of) drgeo image in both runs.
I don't fully trust the MessageTally timings, or at leas I find it hard to
tell where exactly the code runs slow (if at all, as the differences are
small).
And I don't know if this difference in timing is what Hilaire observed, as
he wrote : Pharo3 gets slower and slower for every run. I
could not reproduce this one.
