When test_sockmap was running outside of selftests and was not being run by build bots it was reasonable to spend significant amount of time running various tests. The number of tests is high because many different I/O iterators are run. However, now that test_sockmap is part of selftests rather than iterate through all I/O sides only test a minimal set of min/max values along with a few "normal" I/O ops. Also remove the long running tests. They can be run from other test frameworks on a regular cadence. This significanly reduces runtime of test_sockmap. Before: $ time sudo ./test_sockmap > /dev/null real 4m47.521s user 0m0.370s sys 0m3.131s After: $ time sudo ./test_sockmap > /dev/null real 0m0.514s user 0m0.104s sys 0m0.430s The CLI is still available for users that want to test the long running tests that do the larger send/recv tests.
