Focus of that 'test' was to see how TopMM compares with FastMM (both
Delphi only), which turned out that FastMM is 50% faster than TopMemory.
Which, to me at least, significantly reduces TopMM's desirability until
I find a massively threaded application to test it with.
About that 64bit/32bit issue..
I don't really see what all that fuss was about.
Here are the timings:
And, these are the ratios:
FPC_x86/FPC_x64 = 1.29
Delphi/FastMM = 1.08
FPC/Delphi = 1.61
FPC/FastMM = 1.73
FPC/TopMM = 1.15
TopMM/Delphi = 1.40
TopMM/FastMM = 1.51
On Windows7_x64, *64bit binary* compiled with FPC runs about *30%
faster* than 32bit binary.
I don't have an identical native x86 computer with Windows7_x86 to test,
