    Sounds like a false economy

    If you went to the trouble to optimize the performance of this math intensive app, it seems counterproductive to ignore the huge benefits from SSE/SSE2 that the compiler can give almost for free.

    Presumably it was only a few inner loops that really needed turboing, and a runtime selection of different code paths wouldn't make much of a dent in the 650KB. Not as if it would require significant Q/A either.

    Such is the PHB.

    Wow, talk about trial by fire!

    Heckuva project to cut your teeth on. I can understand how real-world requirements would affect your choices, but if this was all in C then I don't see the boss's reluctance to compile with various optimization flags.

    And really, why wasn't it written in FORTRAN?
