sun (oracle) 7110 zfs low performace fith high latency and high disc util.
...cache hit/sec, 350 data hit/sec 50 data miss/sec) The very strange thing is: we have very high rates at disc percent of utilization (every disc) due to ~3200 iops in the discs (60 iops / data disc) with 0 size if we initiate a sequencial read or write from one of the nfs clients we get 8-15MB/sec performacce from the system. I''d like to know why it is doing that, how can an iops be 0 length, what can we do about it? Thank you for any help, we really need to solve this. -- This message posted from opensolaris.org
