Is this a G4? I'll see what numbers I get on 1GHz G4 eMac the next time 
I get to use that machine. I suppose you are using the latest version - 
Self on the Mac didn't have the SIC (simple inlining compiler) before 
4.2 and didn't even have PICs (polymorphic inline caches) before 4.1.6.

It seems that the compilers have been improved for the Sparc. Here are 
more numbers on that same machine:

Self 4.0 =>  60,150,375 bytecodes/sec; 5,845,070 sends/sec
Self 4.1 =>  78,527,607 bytecodes/sec; 15,404,782 sends/sec

You might also want to run the benchmarks several times. Here are the 
first ten runs in Self 4.1.1 on the Ultra:

  75,029,308 bytecodes/sec; 16,746,759 sends/sec
  74,116,965 bytecodes/sec; 16,915,608 sends/sec
  69,678,824 bytecodes/sec; 16,492,340 sends/sec
  72,480,181 bytecodes/sec; 16,946,674 sends/sec
  97,116,843 bytecodes/sec; 16,962,250 sends/sec
 100,078,186 bytecodes/sec; 16,993,488 sends/sec
 101,910,858 bytecodes/sec; 16,962,250 sends/sec
 101,185,770 bytecodes/sec; 16,977,855 sends/sec
 101,105,845 bytecodes/sec; 17,024,842 sends/sec
  85,106,382 bytecodes/sec; 17,087,897 sends/sec

Please note that these are bad benchmarks for Squeak, and even worse for 
Self (the moral equivalent of BogoMIPS in Linux). For a serious 
comparison we should be using DeltaBlue, Richards and so on.
