Re: Intent to ship: Throttling timeouts in background using execution budget.

Hi! I forgot to mention this issue, thank you for bringing it up. Background throttling is disabled whenever something that is considered real time, like audio, or could potentially time out, like web sockets, is present on he page, including iframes. To both prove to myself that these mechanisms

Re: Intent to ship: Throttling timeouts in background using execution budget.

Yes, there are related telemetry probes, but I've recently convinced myself that they won't be able to clearly detect budget throttling. The probe is TIMEOUT_EXECUTION_BG_MS, and the reason for it not working is that it accumulates execution over one second, which just happens to be the time of the

Re: Intent to ship: Throttling timeouts in background using execution budget.

Thanks a lot for working on this, it sounds awesome! Can I ask if there are any related telemetry probes that will be used later on to evaluate the results and maybe tune these constants? Do you plan to expose any of these parameters to web extensions? Gabor On Thu, Oct 5, 2017 at 5:27 PM, Andrea

Intent to ship: Throttling timeouts in background using execution budget.

Hi all! After Bug 1377766 lands, we will increase the amount timeouts executing in background tabs are throttled, based on an execution budget. This budget is continuously regenerating, and is decreased when timeouts execute. If the budget becomes negative, timeouts will not be allowed to run unti
