We don't always have control over what the user does. I think the worst-case for my users involves a third-party program (that they're not willing to modify) that does line-buffered writes in append mode. This uses nearly all of the CPU on per-RPC overhead (each write is three RPCs: GETATTR, WRITE, COMMIT). -GAWollman _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
