Subject: A Linux TCP SACK Question
Date: Thu, 03 Apr 2008 21:54:22 -0700 [thread overview]
Message-ID: <fc471cb97cfd.47f5520e@fnal.gov> (raw)
Hi, Could any body help me out with Linux TCP SACK? Thanks in advance.
I run iperf to send traffic from sender to receiver. and add packet reordering in both forward and reverse directions. I found when I turn off the SACK/DSACK option, the throughput is better than with the SACK/DSACK on? How could it happen in this way? did anybody encounter this phenomenon before?
thanks,
wenji
