Hi,
We are testing iSCSI performance on SmartOS. We exposed a SSD disk via iSCSI target, and on iSCSI initiator side got a ~250MB/s throughtput. The iSCSI target and the initiator was connected through a 10Gb network. If the target and the initiator run on the same machine (both in the global zone), the throughput is still ~250MB/s. If we write to the SSD directly, the throughput is ~500MB/s. I looked back some old posts before 2010, which mentioned that the low iSCSI performance on Solaris was due to the TCP Nagel algorithm. I am wondering whether it is still the case with current iSCSI implementation in SmartOS. If so, how we can disable the Nagel algorithm in a given SmartOS zone? Tons of thanks.
