So. Is this “official"? There is at least one place in Gecko that we can change from “low memory is <= 256” to “low memory is < 512”, but I don’t really want to do it unless we’re all agreeing to this. Any code in Gaia that is currently doing special things with other numbers will stop, and we’ll just look at < 512mb from now on?
Is it worth having this as a constant/preference? -- - Milan On Jul 28, 2014, at 23:20 , Tim Chien <[email protected]> wrote: > Input management copy the same number (from the same patch) and > running keyboard inproc when memory is < 512mb. > > https://github.com/mozilla-b2g/gaia/blob/be5fc7f8d2bb6f6ad61294a6e2219827b9930901/apps/system/js/keyboard_manager.js#L421-L429 > > On Tue, Jul 29, 2014 at 6:34 AM, Kevin Grandon <[email protected]> wrote: >> Sounds good to me.
