We have a new NAS with 6xSAS in RAID10, testing OpenSolaris 2009.6 on it.
A local read/write speed is amazing, about 700/350MB/sec. The network is temporary set up a s a single 1Gbit link, without any link aggregation/jumbo frames. I get 80/60MB/sec read/write over NFS.
When sharing a volume via iSCSI I get 60MB/sec write speed however a read speed is very slow, about 5-10MB/sec. What could cause this? Tried Linux/Windows iSCSI initators, result is the same.
Thanks for the ideas.
