Hi All,
Looking for some feedback in my test setup...
Can you please review my setup and let me know how to improve my
application of the qdiscs? I've been applying manually, but I'm not
sure that is the best method, or if the values really make sense.
Sorry if this has been covered ad nauseum in codel or bloat threads
over the past 4+ years...
I've been capturing packets on a dedicated monitor box using the
following method:
tshark -i moni1 -w <file>
where moni1 is ath9k on channel 149 (5745 MHz), width: 40 MHz,
center1: 5755 MHz
The system under test is a lanforge ath10k ap being driven by another
lanforge system using ath9k clients to associate and run traffic tests.
The two traffic tests I'm running are:
1. netperf-wrapper batch consisting of: tcp_download, tcp_upload,
tcp_bidirectional, rrul, rrul_be and rtt_fair4be on 4 sta's.
2. lanforge wifi capacity test using tcp-download incrementing 4
sta's per minute up to 64 sta's with each iteration attempting
500Mbps download per x number of sta's.
what results are you getting? and what results are you hoping to get to?

I'll share my results shortly, but the main idea is that I'm doing the
captures as part of our effort to improve the ath10k driver. Just one
comparison is that with many clients the ath10k ap throughput tails off
whereas some non-ath10k ap's are able to sustain high throughput for
many clients, but even that depends on manufacturer and firmware combos.
I'll be able to point this behaviour out better once I get the files
uploaded...
