It sounds to me like you need to disable the Nagle algorithm[1] as described in the workaround section of 6621560[2]. 1. http://en.wikipedia.org/wiki/Nagle%27s_algorithm 2. http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6621560 I suspect that a similar setting may be needed on the Solaris target or the Linux initiator as well.
