Comment:

Gcc 3.1.0 had problems with its optimizer such that it inserted
worthless register loads into the instruction stream -- maybe that bug
is back.....

With gcc 3.1, the performance saw a substantial improvment when it was
compiled with -O0 -- that was not the case this time...

With -O1, however, there was a substantial improvment, though still much
worse than my workhorse VM...


' 72 072 072 bytecodes/sec; 3 465 884 sends/sec. //-march=athlon-mp -O1
' 49 306 625 bytecodes/sec; 1 690 230 sends/sec'  // -march=athlon-mp -O0
