Just looked at TCP tx data for Ch 44 from the logs you provided and I see better throughput on M69 compared to M68. Jeevitha, can you copy/paste the throughput data in the bug where you see the regression?

For ch6 most runs on M69 and M70 show throughput below 40mbps. https://chromeperf.appspot.com/report?sid=bfd1a21dd27393325308a1f018dc00f0f00f26b30c6a9c849890dade1eef8fb8&start_rev=34970191089500700&end_rev=35110001095600000 For ch153, looking at historical throughput data it seems to be inline. The chart below shows data for few different atten values (79 - 91)... https://chromeperf.appspot.com/report?sid=e593a0d7e875a860f39b9c83fce6cfae40336c99bcd1d7d90096df4ec0ea6264&start_rev=32390501003203900&end_rev=35380131102101000 The M68 throughput being higher may be due to the grover setup (old vs. new). Aashutosh, do you have the test logs for the M68 atten perf run that you kicked off to collect that data? |
