if a bug fixed in Illumos is never reported to Oracle by a customer, it would likely never get fixed in Solaris either :-( I would have liked to think that there was some good-will between the ex- and current-members of the zfs team, in the sense that the people who created zfs but then

Ok. I blew it. I didn't add enough information. Here's some more detail: Disk array is a RAMSAN array, with RAID6 and 8K stripes. I'm measuring performance with the results of the bonnie++ output and comparing with with the the zpool iostat output. It's with the zpool iostat I'm not seeing a lot

what is zpool zpool status are you using the default 128k stripsize for zpool is your server x86 ? or sparc t3 , how many socket? IMHO, t3 for oracle need careful tuning since many oracle ops need fast single thread cpu Sent from my iPad On Jan 5, 2012, at 11:40, grant lowe glow...@gmail.com
