#9 QuickPar for win32 seems to run MUCH faster... Improve Speed

[Michael J Evans]

It seems to take a Lot longer to do anything on my linux system
then on the Win32 system. True, the systems don't have the
same CPU, however one's an athlon tbird 1ghz, and the other is
an Athlon XP 2.2 (1800 clock) so the speed isn't THAT much
different for what seems like a major difference in speed.

Maybe it's the memory, Maybe it's the 2x speed increase in the
CPU, however it doesn't seem like it should be This slow.

QuickPar is quicker than par2cmdline as a result of two main
differences:

1) It uses asynchronous file I/O to prefetch file data whilst
processing continues.

2) It uses hand written assembler code for the most CPU
intensive parts of the code.

Because par2cmdline needs to be portable, these two
optimisations have not been implemented. They may be
implemented in the future, but that is likely to occur on an ad
hoc basis.

PS You forgot to mentian what the speed differential was.

I have noticed this with the Par2cmdline and quickpar 0.9.1 as well.
