From 760d0df3add547b78dc51206af07dba38fbac3c0 Mon Sep 17 00:00:00 2001 From: "Matthieu Baerts (NGI0)" Date: Wed, 31 Jan 2024 22:49:51 +0100 Subject: [PATCH] selftests: mptcp: decrease BW in simult flows [ Upstream commit 5e2f3c65af47e527ccac54060cf909e3306652ff ] When running the simult_flow selftest in slow environments -- e.g. QEmu without KVM support --, the results can be unstable. This selftest checks if the aggregated bandwidth is (almost) fully used as expected. To help improving the stability while still keeping the same validation in place, the BW and the delay are reduced to lower the pressure on the CPU.
