Let me guess: Intel ICH5 or 6300ESB south bridge and ATA disk (Seagate Barracuda 7200.7)?
There is something wrong in the RELENG_5 ATA driver that makes this combination perform really slow on writes (~16MB/s). When connecting a nearly identical SATA drive to the machine it performs as expected with ~55MB/s sequential writes.
RELENG_4 performs as expected and I think ATA mkIII in CURRENT also works. /Martin _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
