Subject: poor sctp performance with small packets
Date: Wed, 16 Mar 2011 14:45:10 +0100 [thread overview]
Message-ID: <20110316134510.64770@gmx.net> (raw)
Hi,
I am just trying iperf 2.0.8 with the "-z" option - packet size is 1 Byte.
(With my own tool the results are the same)
./iperf -s -p 4444 -l 1 -z (this is the reader)
./iperf -c 172.16.0.1 -l 1 -p 4444 -t 30 -z (this is the writer)
>From a tcpdump point of view it looks that only each 200ms a packet is sent - so very poor throughput.
OS is Redhat,
