I'm running open-iscsi with scst on Broadcom 10Gig network and facing write latency issues. When using netperf over an idle network the latency for a single block round trip transfer is 30 usec and with open-iscsi it is 90-100 usec.
I see that Nagle (TCP_NODELAY) is disabled when openning socket on the initiator side and I'm not sure about the target side. Vlad, Can you elaborate on this? Are others in the mailing list aware to possible environment changes that effext latency? more info - I'm running this test with Centos5.3 machines with almost latest open-iscsi.
