A co-worker is putting together a system to host a ZFS NAS, and is using the same motherboard that you are. He had the board's manual with him, and I noticed that there are BIOS settings for the pcie max payload size. The default value is 4096 bytes. This doesn't help explain why the throughput dropped when increasing max_payload_size over 512 causes a drop in throughput, but at least you can safely run the card with a payload greater than 128. -B -- Brandon High [EMAIL PROTECTED] "The good is the enemy of the best." - Nietzsche _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
