Re: [Bloat] [Rpm] Open Loaded latency data from ookla

[Sebastian Moeller <moeller0@gmx.de>]

Hi All,

We are getting there...

'The average latency of all tests performed in the tile, represented in milliseconds'

This is infinitely better than no under-load numbers. However, the latency distribution is neither 'normal'* nor fully symmetric (it can not, there is a hard minimum, the minimal path RTT and a hard maximum (icmp timeout) even though the distribution will likely be closer to the minimum than the maximum)**.

Next improvement possibility: they report averages and number of tests, but no measure of variance... 

To put a positive spin on it, reporting luli numbers at all is great, as is the potential to improve the reporting quality with small additions!

Regards
        Sebastian

*) Which is not a showstopper per se as long as the distribution is unimodal and not too skewed then the average is still intuitively interpretable, but is it?
**) My gut feeling is a beta distribution could be fitted to the data and that functions control parameters reported to better model the expected distribution shape.

P.S.: This time without links to test what triggers getting blocked...
