Thanks for your response. Yes, we can know whether the program is I/O bound or CPU bound by time(1). But it is still unclear which part of the program is really waiting for I/O. So profiling is needed for tuning, although CPU time profiling gives me non-distinct result on I/O bound programs. It is reason why I want wall-clock time profiling. -- Akihiro KAYAMA _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
