How about tcp window size (particularly tcp_recv_hiwat on the recv side) and whether or not some CPU is saturated (particularly the interrupt cpu on recv side, check with mpstat 1). There is also some magic incantation to allow bigger transfer size in iscsi (blaise should have the details). Can you verify the single connection throughput using either of iperf,uperf,netperf. -r > > -- > This message posted from opensolaris.org > _______________________________________________ > zfs-discuss mailing list > zfs-discuss@opensolaris.org > http://mail.opensolaris.org/mailman/listinfo/zfs-discuss _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
