No - I could not reproduce it.  I tried with a recent Trunk image and
a Squeak 3.8-derived image (Etoys) and consistently got times within
10% to 20% of each other.   I used an Intel dual core, with fairly
recent 32-bit Mac OS X builds of the virtual machine:

Value of
SmalltalkImage current vmVersion
in these two instances is

 'Squeak3.8.1 of ''28 Aug 2006'' [latest update: #6747] Squeak VM 4.2.4b1'
'Squeak3.8.1 of ''28 Aug 2006'' [latest update: #6747] 4.0'

Hope that helps.
