...same happened here. For the comparision, on an Intel Pentium/M 1.73 GHz  
(windoze xp) with JSE2:

SqueakOnJava:   7,684,918 bytecodes/sec;   440,641 sends/sec
SqueakOnC:    273,066,666 bytecodes/sec; 8,158,635 sends/sec

And the .class files in sSqueakOnJava.jar are unbelievable small, great  
work!
