Intel has a compiler that you Linux folks might want to try. I know that the purse strings of a Linux user are bound at 100 million PSI, but you could try a *free* evaluation at least, and see how it compares. I am predicting double the speed. Note that I am not talking about the KAP compiler for Linux (but rather) the Intel C++ compiler 6.0 for Linux (which is now in beta).
