concurrent.futures uses polling in its worker threads and processes
(with a timeout of 0.1).
It means that:
1) this prevents CPUs to enter low power states durably
2) it incurs latency when calling shutdown() on an executor (this seems to be the main source of slowness in test_concurrent_futures under Linux) |
