I have the results of two actual runs, one using Djgpp's GCC in a DOS box and the other Borland's C++ Builder with the same CPP source. The program which processed a 255 Mbyte text file. Djgpp finished in 10 min 31 sec, the Builder in 17 min 3 sec. The cause of this difference must be the inefficiency of the Windows implementation of the FAT32 file system. The same program compiled in Linux and run on the same machine using the same FAT32 file system mounted under /dos/d finished in 1 min 21 sec... I understand that this is not simply a compiler test, but it is interesting nevertheless... _______________________________________________________________ Question #7: How Can I Make Linux More Like Windows?
