Every microsecond counts. I am presently having to design a disgusting hack in the kernel which allows our traffic generator to run in the kernel because it is not possible to fill an Ethernet with minimum-length UDP packets when crossing the system call boundary. As for the `off_t' question: you will never convince me that the Berkeley people did not do the right thing. I still hold out hope that it will be possible to create a proper ISO C environment for FreeBSD in which CHAR_BIT*sizeof(long) == 64. -GAWollman -- Garrett A.
