Hello Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/upf-benchmark/+/39890?usp=email to look at the new patch set (#2). The following approvals got outdated and were removed: Verified+1 by Jenkins Builder Change subject: testsuites: upf: Support setting net iface irqs in c240 host ...................................................................... testsuites: upf: Support setting net iface irqs in c240 host The Cisco C240 machines consist of 2 CPU packages, each with 20 cores (hyperthreading disabled). Those 2 CPUs packages are hence placed in 2 different NUMA zones. By default, mlx5 driver creates one rx-queue per core, in this case it creates 40 rx-queues with 40 irqs (one for each rx-queue/core). This means it doesn't take into account the fact that the network card is plugged into a given PCIe bus belonging to one of the 2 available NUMA zones. As a result, when a packet is received and put into the rx-queue+irq belonging to the other NUMA zone, a penalty in memory-bandwitch is incurred, which ends up in a performance throughput penalty. This commit is similar to 224e2dc3ab67311b4bad94bf891d1b5c5ca6128f applied to the tunmap scenario.
