From a quick look at telemetry from bug 1576507 so far (https://sql.telemetry.mozilla.org/queries/64937/source) we see far more time-outs than expected (I have never seen them locally even on a very slow connection).

Right now we only record if a time-out occurred but not how long it took, and time-outs are hardcoded to 5 seconds. Let's:

  1. bump the time-out to something much higher (30s?)
  2. record the number of seconds elapsed

Having the distribution of seconds elapsed should help us to determine a better default, and also let us dig into why this might be happening for some users and not others. A few guesses are things like type of drive (SSD or not) and presence of anti-virus.

DATA COLLECTION REVIEW RESPONSE:

    Is there or will there be documentation that describes the schema for the ultimate data set available publicly, complete and accurate?

Yes. This collection is Telemetry so is documented in its definitions file [Scalars.yaml](https://hg.mozilla.org/mozilla-central/file/tip/toolkit/components/telemetry/Scalars.yaml) and the [Probe Dictionary](https://telemetry.mozilla.org/probe-dictionary/).

    Is there a control mechanism that allows the user to turn the data collection on and off?

Yes. This collection is Telemetry so can be controlled through Firefox's Preferences.

    If the request is for permanent data collection, is there someone who will monitor the data over time?

No. This collection will expire in Firefox 75.

    Using the category system of data types on the Mozilla wiki, what collection type of data do the requested measurements fall under?

Category 1, Technical.

    Is the data collection request for default-on or default-off?

Default on for all channels.

    Does the instrumentation include the addition of any new identifiers?

No.

    Is the data collection covered by the existing Firefox privacy notice?

Yes.

    Does there need to be a check-in in the future to determine whether to renew the data?

Yes. :rhelmer is responsible for renewing or removing the collection before it expires in Firefox 75.
