Hi, A dual test means that you are sending the receiving simultaneously. Your network is probably "Full Duplex" so the maximum bidirectional bandwidth is 200Mbit ( minus protocol headers ).

Subject: [Iperf-users] IPerf 2.0.8 Dualtest Hello, I have done a dualtest with iperf: On server I execute: iperf -s And on client: iperf -c <server_ip> -d The output shows me in addition more bandwidth than my network (100MBit/s) has: [ 5] 0.0-10.0 sec 103 MBytes 86.6 Mbits/sec [ 4] 0.0-10.0 sec 101 MBytes 84.4 Mbits/sec That is approxiametly 170 MBits/sec and not 100 MBit in maximum. I searched the web for the problem, but the only reason I found is the window size. I changed it between 50 kb and 1500 kb on client and server but it has no effect (perhaps 5MBit/s). Is there an other explaination for my problem? Regards Frank ______________________________________________________ GRATIS für alle WEB.DE-Nutzer: Die maxdome Movie-FLAT!
