Re: [Flent-users] [tohojo/flent] flent: extremely high ping times on macOS (#178)
I am going to close this for now. Two reasons: 1. The primary reason for this report was that I misunderstood how Flent measures latency for its default plot. Currently, that plot shows latency to the -H host. As noted in https://github.com/tohojo/flent/issues/181#issuecomment-530500478, there could be an option to substitute a nearby host for default ping measurements. This would be great because the measured latency would likely have lower variance, and any induced bloat would be a larger percentage of the total. 2. I can no longer reproduce the difference between Flent's reported latency (say, to ping_host) and a separate fping session. My original measurement process might have been faulty - I can no longer say how I got those values. Thanks. -- You are receiving this because you are subscribed to this thread.

See [Coffee Shop Bloat Script](https://github.com/richb-hanover/coffee-shop-bloat-test) I can conceal a lot of the options into the script if I know what they are.

Re: [Flent-users] [tohojo/flent] flent: extremely high ping times on macOS (#178)
Hmmm... The `--test-parameter=ping_hosts=gstatic.com` information appears in the command-line summary but not in the charts. Is this correct? If so, the charts display significantly different latency depending on which -H host gets used. The Terminal display (bottom) shows fairly consistent ping times and transfer rate measurements using either of the two hosts. This raises two questions: 1. Could flent charts use the `--test-parameter=ping_hosts=...` instead of values from the -H host? 2. Why is there a discrepency between the `--test-parameter=ping_hosts=...` reading (showing 30-38 msec in my tests) and a separate, concurrent fping test (see original post, where it was running 20-22 msec)?
