Hello Dave, Do you still have that measurement data available and/or the scripts that were used to collect that data ? I'd like to have a look at which test you ran such that I can repeat that test with Linus' master tree. A lot has been changed since kernel 2.6.38 was released, e.g. several more SCSI core and SRP initiator driver optimizations have been accepted upstream since then. I have found an e-mail from you from 2010 with measurement data attached in an .ods document but it's probably not that e-mail that you are referring to (http://www.spinics.net/lists/linux-scsi/msg49216.html). Thanks, Bart. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
