+With the simulated bad network (with added 500 ms latency and throttled to 100 KB/s), the tests 
 should still complete successfully, it'll just take a bit longer. For example on an M1 Max, it
 typically takes around 1m 25s with the bad network simulation, and around 50s with non-degraded
 network.
