Hey Yoric, Do we have any idea whether this has an impact on energy use? >
I think it's plausible, but I don't think we have a super great way to measure that out in automation or with Telemetry (we might be able to use things like the Intel Power Gadget to measure locally). The original intent, however, was not to improve battery life (although that'd be a pleasant side-effect!), but rather to improve responsiveness and page load time (the theory being that processes hosting only background content tabs can't steal as many cycles from foreground tabs). Responsiveness and page load time is what I'm hoping to pay attention to - although if people see battery usage improvements, that's great too. :) -Mike On Tue, 29 Jan 2019 at 13:49, David Teller <dtel...@mozilla.com> wrote: > This sounds like a very good thing to have! > > Do we have any idea whether this has an impact on energy use? > > On 29/01/2019 19:32, Mike Conley wrote: > > (cross-posted to dev-platform and firefox-dev) > > > > Hi folks, > > > > Just a heads up that in bug 1476981 > > <https://bugzilla.mozilla.org/show_bug.cgi?id=1476981>, I just > > autolanded a patch that, when hopefully merged, will enable the Process > > Priority Manager for Firefox Desktop on Nightly on Windows. > > > > The Process Priority Manager lowers the OS-level process priority for > > any content processes that host /only/ background tabs.
