I'm only logging the send rate. I don't care what the workers receive. I would expect the send rate to be constant since the master is always doing the same amount of work. Here's some numbers: Rate for 1 workers: 249353 Rate for 2 workers: 220569 Rate for 3 workers: 213680 Rate for 4 workers: 205965 Rate for 8 workers: 147463 (the machine has 12 cores) > Re: hyperthreading, if that's enabled test with num_workers = num_cpus > / 2 (and pin each worker to a separate physical CPU.
