Higher speeds from 2.0 vs. 1.0

Open laiyi-ohlsen opened this issue 4 years ago • 5 comments

User reported issue:

For Platform 2.0, the upload speeds are slightly higher, but only by about 10-15%, and they immediately plateau again. Note that on the two charts, the Y axis is different!

Note that my download speeds are slightly higher than the M-Lab viz on the Web — the viz shows 17.4 at the first of November 2019. I had about 22.5 for the month of October 2019. The difference may be that I use the maximum speed test per day per client which would likely lead to a more optimistic number.

Quick note: Ideally we should always prefer plotting with log Y axis, and never average across clients, as that gives far too much weight to fast clients.

I typically take the median across the clients, and the max per day within the client. You can see the mean across clients, but that's not the recommended view within I3.

Got it. Didn't know who made the plots, and like to remind people that averages are very sensitive to how many fast clients are running tests.

This probably belongs in another repo. etl just does the parsing, and this is more associated with either the server or the platform or both.

At least one problem is in the parser/views, and legacy issues in the platform itself are not actionable.
