From e516809a74ffd495481a7adf6b565181861a41f9 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Mon, 6 Nov 2023 18:08:28 +1100 Subject: test/perf: Start iperf3 server less often Currently we start both the iperf3 server(s) and client(s) afresh each time we want to make a bandwidth measurement. That's not really necessary as usually a whole batch of bandwidth measurements can use the same server. Split up the iperf3 directive into 3 directives: iperf3s to start the server, iperf3 to make a measurement and iperf3k to kill the server, so that we can start the server less often. This - and more importantly, the reduced number of waits for the server to be ready - reduces runtime of the performance tests on my laptop by about 4m (out of ~28minutes). For now we still restart the server between IPv4 and IPv6 tests. That's because in some cases the latency measurements we make in between use the same ports.
