Hi Enrico,
For what it's worth, here is the data you wanted :)
OS: Windows XP Prof. with SP2
Processor: Intel P4 3 GHz with HT
RAM: 512 MB, ~155 MB free
Tested against the code supplied in your earlier mail.
Compilers Tested: 1. MingW with GCC 3.4.2
2. MS Visual C++ 2003 (7.1)
3. MS Visual C++ 2005 (8.0) BETA
MingW MSVC7.1 MSVC8.0
Default 3.5310 3.1090 3.0930
Maximize Speed 0.1560 0.0000 0.0000
[-O3] [\O2]
[\O2]
All the tests were run 5 times, and the lowest execution time was noted.
Hope this helps :)
