...my throughput for a total of 1280 seconds. This is significant! There is definitely a relation with the database checkpoints that when happening consequently make the long fdsync show up. I would like to delve in a little deeper. It could be the sheer number of pages that are being written due the fdsycn. Wonder if someone has a dtrace script snippet I could use here to understand a little better what is going on under the hood. BTW running ZFS where my intent log is on a RAID array which has 1GB of write caches. Thanks, Paul -- This message posted from opensolaris.org
