Web11 mei 2015 · The UDP tests with the -u argument will give invaluable information about the jitter and the packet loss. If you don’t specify the -u argument, Iperf uses TCP. To keep a good link quality, the packet loss should not go over 1 %. A high packet loss rate will generate a lot of TCP segment retransmissions which will affect the bandwidth. WebThis means that you can measure latency of single packets even under a load of millions of PPS (without waiting for reply of packet before sending a subsequent packet on time). Enables spike analysis by providing in each run a histogram with various percentiles of the packets’ latencies (for example: median, min, max, 99% percentile, and more) in … Web27 feb. 2024 · iperf can be used to collect latency and bandwidth statistics for both TCP and UDP. It uses a client server model, where data can be analyzed from both ends. Among stats it can collect – throughput, jitter, and packet loss. This is basically a tool to measure overall link quality. It does not measure application performance. high volcano in europe
