Web19 aug. 2014 · All current RPi models have a 10/100 interface, so the maximum theoretical bandwidth they can push is 100Mbps. Note that Iperf is CPU intensive and the maximum achievable bandwidth is also limited by the RPi’s CPU capabilities. If you are not running any other heavy applications on the RPi, you might be able to achieve up to 75Mbps.

So if there is a bandwidth limit, we only need to delay the packets, and TCP will automatically adjust to it. But in UDP there is no such thing. So when the packets are delayed, they will pile up, and we cannot do anything …

WebIf there are multiple streams (-P flag), the bandwidth limit is applied separately to each stream. You can also add a '/' and a number to the bandwidth specifier. This is called "burst mode". It will send the given number of packets without pausing, even if that temporarily exceeds the specified bandwidth limit.
