* test/perf: Actually load passt enough to test UDP performanceStefano Brivio2021-10-212-26/+26
| | | | | | | | | With recent improvements, we're not CPU-bound at all while testing UDP performance. Give the VM more memory and CPUs, forward two additional ports, start up to four threads in parallel, and give single iperf3 threads higher bandwidth targets.

* test/perf: Try sourcing maximum scaling frequency from cpufreqStefano Brivio2021-10-214-4/+14
| | | | | | | On most recent CPUs, that's a better indication of all-core turbo frequency, or non-turbo frequency, than /proc/cpuinfo. Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
* perf/passt_udp: Don't overshoot UDP bandwidth excessively on larger MTUsStefano Brivio2021-10-191-2/+2
| | | | | | | ...performance with 64KiB MTUs might look worse than with 9000bytes on some configurations. Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
* perf/passt_tcp: Don't exceed typical L3 cache sizes with buffersStefano Brivio2021-10-191-8/+8
| | | | | | ...we might see misleading rate drops with larger MTUs otherwise. Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
* test/perf: Use CPU frequency from /proc/cpuinfo instead of cpupower(1)Stefano Brivio2021-10-194-8/+8
| | | | | | Get it to work also in nested virtualisation environments. Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
* test: Add CI/demo scriptsStefano Brivio2021-09-274-0/+859
Not really quick, definitely dirty. Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
