I applied your patch to a current as of July the 31'st. I had to remove /usr/src and perform a clean csup and remove the two empty files as mentioned in this thread. I have a areca arc-1680 sas-card and an external sas-cabinet with 16 sas-drives each 1 TB (931 binary GB). They have been setup in three raidz-partitions with five disks each in one zpool and one spare. There does seem to be a speed-improvement. I nfs-mounted a partition from solaris 9 on sparc and is copying approx.400 GB using rsync. I saw write of 429 MB/s. The spikes occured every 10 secs. to begin with. After some minutes I get writes almost every sec. (watching zpool iostat 1). The limit is clearly the network-connection between the two hosts. I'll do some internal copying later. It's to early to say whether zfs is stable (enough) allthough I haven't been able to make it halt unless I removed a disk. This was with version 6. I'll remove a disk tomorrow and see how it goes. -- regards Claus When lenity and cruelty play for a kingdom, the gentlest gamester is the soonest winner. Shakespeare
