I'm messing arounds with MPW builds of Squeak, using various types and 
levels of optimization.  Got the thing running (at last) consistently with 
all capabilities (some significant reorganization of interp.c is necessary 
to compile under -opt speed; some magic is necessary to get named 
primitives internal to the VM to work right), but I'm concerned that the 
supposedly "highly optimizing" MrC may not have produced the best results 
possible.

Which benchmarks, whether or not found in the standard image, have people 
found to be most meaningful/relevant to evaluation of a squeak build? 
Unsurprisingly, I have found the several benchmarks yielding quite 
different results?

Is there a benchmark suite people rely upon to evaluate whether a change is 
an improvement?  If not in the standard image, where would I found them.
