So they are providing both transport and bandwidth?
Is the gigabit limit imposed by some sort of rate limiting mechanism, or is it actually a 1 gigabit physical circuit?

Have you captured the speedtest with a capture tool (wireshark) and looked for retransmissions? Even though it has largely not a problem anymore, latency can affect TCP/IP performance. Also, even tiny packet loss can cause problems in obtaining full speed. Is their iperf server perhaps running UDP and yours running TCP?

We have a circuit with a fiber provider that aggregate at prime time can hit 800mbps download. However, with a high end laptop connected directly to the fiber NID we can’t get more than 200-250mbps sustained download to any speed test (speedtest.net <http://speedtest.net> , fast.com <http://fast.com> , speed.ui.com <http://speed.ui.com> ) and it just starts slowly going down. Upload is around 800mbps. Same laptop on a Level3 circuit will easily hit gigabit in both directions. We setup an iperf server and see the same thing. The provider brings an iperf server in and they can hit the proper speeds going to an off net iperf server they have. Provider speed tests to our iperf server and gets the slower speeds. They say because they can’t find an issue when using their iperf server there is no issue. I don’t even know what to suggest at this point. -- AF mailing list AF@af.afmug.com <mailto:AF@af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- - Forrest
