Hello, here with the latest results, with a home-made mapserver 3.5:

754594 microseconds   4.2.3 (home-made, VC++6)
823738 microseconds   4.2   (UMN binaries)
816582 microseconds   3.6.7 (UMN binaries)

669673 microseconds   3.5   (home-made, VC++6)
564443 microseconds   3.5   (home-made, MinGW)
324430 microseconds   3.5   (msexplorer MinGW DLL)

4.2 is not really slower, MinGW seems to produce faster code, and I
absolutely don't understand why msexplorer DLL is so fast.
