For a long time the gcc optimizer simply wouldn't work for building
Squeak on ARM. I think the problem version(s) was about 2.95-ish. On
the old NetWinders that made for approx a halving of performance.

My 600MHz XScale 80321 machine does around 25-30 mBC/sec (depending on
the phase of the moon it seems) and 1-1.2 milion sends/sec (likwise).
Since bytecode loops will scale roughly with cpu speed  and sends/sec
roughly with memory speed, you should be able to get a bit better out
of your stix.
