Oh come on now; it probably just needs someone to tweak the knobs on the back
of the set... (twiddle twiddle)..
How's this 3.03 result:
0 tinyBenchmarks
'47442550 bytecodes/sec; 1434550 sends/sec'
'47761194 bytecodes/sec; 1415033 sends/sec'
For reference, 2.95.3 was:
'42553191 bytecodes/sec; 1283021 sends/sec'
'42356055 bytecodes/sec; 1282033 sends/sec'
I used
CFLAGS= -I/usr/X11R6/include -g -O3 -DLSB_FIRST=1 -funroll-loops -fno-gcse
Adding the -fno-gcse made quite a bit of difference (27% more
bytecodes/second, 11% more sends/sec).
So now it's about 12% faster than the 2.95.3 was. Of course, I don't know
what'll happen if you use "-fno-gcse" with the 2.95.3 ...
