Add telemetry for monitoring PBackground-Http performance
No description provided.
bill: do you know if we've already got telemetry probes for main thread event queue delay/waits? We're thinking that might be a likely metric that we'll want to look at here.
Bug 1303296 is probably the best thing, but it's still in progress. BHR covers event loop hangs >= 128ms. Perhaps for big pages we might see an improvement there too. You can also get a sense for how long we're currently spending on the event loop through MAIN_THREAD_RUNNABLE_MS (which is keyed on the runnable name). As long as the runnables you're eliminating are named, you can see how much time you'll be taking off the main thread. But that's a less direct measurement.
