Re: [WISPA] looking for iperf test site with 1G open
Testing to a dedicated Cogent server in California yielded the best results; however, even testing to their pool of iperf servers provided a transfer of 796 Mb/s. The trick was to run multiple threads (50).

Re: [WISPA] looking for iperf test site with 1G open
Want to remind on the Latency factor versus window size that will limit the maximum speed possible to transfer per TCP session. To test 1G, you really need to have a near by low latency site to test to, to get accurate result for a single session. And may be impossible to fill capacity without multiple sessions. You'll probably have to use UDP to test for capacity. Testing TCP quality will be a bit tougher.

Re: [WISPA] looking for iperf test site with 1G open
So, I have a friend that tried that once. It can be pretty hard to get decent speed with bittorrent on a stock system. Lots of different clients, all requesting different data. Plays havoc on drives. Need plenty of cache. RAID0 disk array, etc. On top of that the linux distributions didn't seem to have that much demand, relatively speaking (FTP mirror sites across peering seem to perform better for me). To actually get enough demand to drive the throughput we wanted we had to resort to unmentionable yet far more popular content. But yes, quite fun to take something common and tune it to perform at uncommon loads. On Thu, Apr 15, 2010 at 3:11 PM, Josh Luthman wrote: > Torrents will fill capacity much better.

According to the page above RB750G doesn't have the "all-port-switch" option of RB450G, which suggests it only has one gigabit connection to the CPU. The fact that all RB750G ports have the same MTU (http://wiki.mikrotik.com/wiki/Manual:Maximum_Transmission_Unit_on_RouterBoards), when RB450G Ether1 has a slightly larger MTU than RB450G Ether2-5 suggests that as well.
