1793975 - Add a telemetry probe to measure time spent relaying response start from the parent process to the child

Status: RESOLVED FIXED

(Core :: Networking, task, P2)

Description

[Andrew Creskey | PTO until Sept 15 [:acreskey]]

We receive the server response for an HTTP request on the socket thread of the parent process.
There is a delay in relaying this to the content process - we should measure to see if it can be improved.

As this time is spent entirely within gecko, it would be useful to measure it to see if it can be improved.
