Even if the application were run as a kernel module, how much of a performance benefit could there be when making system calls? I suspect that the module would get a higher scheduling priority but realistically wouldn't the module still have to make system calls in the same manner that a regular user process does? I really don't know, so would some kind soul tell me please? -Zera Holladay _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
