To run, use:
VALGRIND=0 TEST_BENCH=1 eatmydata pytest tests/test_connection.py::test_bench
Example of running on my laptop (without --enable-debugbuild, over of 10 runs):
FAILED tests/test_connection.py::test_bench - assert 47.403406-49.191765(48.343+/-0.48) == 0
With eatmydata:
FAILED tests/test_connection.py::test_bench - assert 25.867860-27.549878(26.5762+/-0.5) == 0
You can also run perf on l1 once it's running:
perf record --call-graph dwarf -q -p $(cat /tmp/ltests-*/test_bench_1/lightning-1/lightningd-regtest.pid)
Then ^C after 10 seconds and run "perf report".
