[Flent-users] [tohojo/flent] Release v2.0.1 - Flent v2.0.1
Released on 2021-06-24. Changes since v2.0.0 include: - Fix globbing in plot and test definitions so it works on newer Python versions - Don't hang forever while trying to process invalid time series data, and check fping timestamp output before using it (fixes a hang bug when using certain versions of fping on BSD and OSX) - Don't crash on metadata collection if hexdump is not available on the system. - Clarify that the Flent license doesn't apply to its output -- You are receiving this because you are subscribed to this thread.

[Flent-users] Announcing Flent v2.0.1
Hi everyone This is to announce the release of Flent v2.0.1. This is a small bugfix release fixing a few annoying bugs affecting plotting on newer Python versions, and running tests on OSX with buggy fping. Changes since v2.0.0 include: - Fix globbing in plot and test definitions so it works on newer Python versions - Don't hang forever while trying to process invalid time series data, and check fping timestamp output before using it (fixes a hang bug when using certain versions of fping on BSD and OSX) - Don't crash on metadata collection if hexdump is not available on the system. - Clarify that the Flent license doesn't apply to its output As always, the Flent source is available via PyPi.

[Flent-users] Re: [tohojo/flent] Plots are broken somehow (#227)
@dtaht it's a BCM4359 with bcmdhd driver (amlogic fork). FullMAC architecture doesn't let us use airtime fairness. So we did some job to decrease buffering inside the driver, we turned off power_save, roaming, periodic scans, background scanning. We also use a combination of fq_codel qdisc for wlan0 interface and BBR tcp congestion algo. bcmdhd driver do some weird things. According to my limited understanding tx_glom and rx_glom work independently from kernel scatter-gather mechanism. So a bunch of tx frames would be splitted and aligned according to tx_glom bucket size every time we try to send something. This chip uses single queue for tx and rx, so according to it's architecture there is no way to achieve low delay with medium and heavy traffic scenarios. Nowadays many android devices use this driver without any optimizations. And it works awful with pfifofast qdisc which is default for android. So much to improve... P.S. It looks like the default fq_codel interval (100ms) is not enough for mobile devices in some scenarios. 300ms ought to be enough for everybody. -- You are receiving this because you are subscribed to this thread.

It looks like we lost the g+ thread but basically we suppressed channel scans if the existing rssi was < 80 or so. -- You are receiving this because you are subscribed to this thread.

[Flent-users] [tohojo/flent] Unable to run Flent test on MacMini/MacOS - Test is not terminating (#228)
Flent test will not terminate and need Ctrl+c to terminate. Looks like
underneath tests are running good, mostly unable to collect results and in loop.
I tried on MacOS-Bigsur, Catalina, Mohave
Test setup:
DHCP Sever -
|---> Mac Mini WAN client
|---> AP -> Mac Mini WiFi client
Running netserver on `Mac Mini WAN client` and Flent on `Mac Mini WiFi client`
Installation step:
1. brew tap kris-anderson/netperf
2. brew install netperf-enable-demo
3. brew install fping
4. pip3 install matplotlib
5. pip3 install flent
6. pip3 install pyqt5
Test debug log - Used third party netserver- `netperf-west.bufferbloat.net`
```
