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 :) Tanuj On 10/17/05, Enrico Migliore <[EMAIL PROTECTED]> wrote: > > >Hi, > > I can confirm Jerome's results.
