I'm not sure that will achieve anything - it's not that I don't
believe you, it's just that I'm not seeing the same thing.
I have now tried on a number of other machines, and the results
are summarised in the following table:
Standard Computed Gotos
Interpreted Compiled Interpreted Compiled
A 3.35 33.56 4.63 (+38%) 29.83 (-11%)
B 5.69 85.24 14.08 (+147%) 78.60 (-8%)
C 15.09 314.91 31.83 (+111%) 259.34 (-18%)
D 45.87 774.73 62.37 (+36%) 795.30 (+3%)
Machine A is a 90Mhz Pentium running RedHat 7.1 with gcc 2.96
Machine B is a Dual 200Mhz Pentium-Pro running RedHat 6.1 with egcs 1.1.2
Machine C is a 733Mhz Pentium III running FreeBSD 4.3-STABLE with gcc 2.95.3
Machine D is an 1333Mhz Athlon running RedHat 7.1 with gcc 2.96
Clearly the speedup varies significantly between systems with some
giving much greater improvements than others.
One other thing that I did notice is that there is quite a bit of
fluctuation between runs on some of the machines, possibly because
we are measuring real time and not CPU time.
