A while ago I came to a similar conclusion. A 1.13 ghx win2000 laptop
was faster than my 1.4 ghz linux AMD.
There must be compiler optimizations available on the ms platforms
that are not there on the other platfforms.

------------- my old message --------------
here are my current numbers comparing IDLDE 5.5 on:
1) 1.4 ghz Athlon 512Mram (Desktop) running Redhat 7.2 Linux
and the KDE desktop
2) 1.13Ghz Pentium III 512Ram (Laptop) running Windows2000 SP2

These were all averaged repeated runs, no "compile time".

Time_test.pro
1 (1.4Ghz Athlon) = 0.78 seconds
2 (1.1Ghz pentium) = 0.63 seconds

Time_test2.pro
1 (1.4Ghz Athlon) = 2.00 seconds
2 (1.1Ghz pentium) = 1.64 seconds

So, the athlon is .78/.63 = 23% slower,
or 2/1.64 = 21% slower.

Of course, clock down the athlon to 1.13 ghz
and the time is 2.00*1.4/1.13 = 2.47 seconds,
and the percent slowness would be
2.46/1.64 = 50% slower.Here is a long url to that
