Web7 feb. 2016 · The phy rate is the speed negotiated between the client and the access point. This "rate" can go up or down based on RF conditions and protocol overhead, but it does not guarantee throughput. It is like being on the expressway and the speed limit is 65, but because of traffic you can only go 20. Web1. IP works by choosing the best route from source to destination. Loopback within a host is better than the Ethernet interface out from a host, so even if you think you are testing the Ethernet loop you wired between your two network adapters, you will find that the traffic sent between two IP addresses of your machine does not pass through it ... Web18 apr. 2013 · A single iperf flow with a 8KB buffer size is not representative of a production enviornment, which would likely have many active hosts in a single LAN. If you are trying to optimize TCP throughput for a single flow, increasing packet payload size and TCP windows are your best bets. If you can decrease the round trip time, that is also valuable. cub cadet csv 070 chipper shredder vacuum
