Bug 1263355 seems to have increased installer size on a number of platforms (by several hundred kilobytes). This isn't an emergency, but I thought I'd file a bug since it's not obvious why this is the case. -- We have detected a build metrics regression from push bd702fa23037799ab4dd266d8a2b59d021f6cfa8. As author of one of the patches included in that push, we need your help to address this regression. Regressions: 0% installer size summary windowsxp opt 53543328.5 -> 53769492.83 0% installer size summary windows8-64 opt 57545770.75 -> 57773071.08 0% installer size summary windowsxp debug 66694903.08 -> 66925550.5 0% installer size summary windows8-64 debug 79563960.58 -> 79834847.58 0% installer size summary windows8-64 pgo 57871511 -> 58041646.42 0% installer size summary linux32 opt 56394272.25 -> 56556170.83 For up to date results, see: https://treeherder.mozilla.org/perf.html#/alerts?id=2719 You can find links to graphs and comparison views for each of the above tests at: https://treeherder.mozilla.org/perf.html#/alerts?id=2719 On the page above you can see an alert for each affected platform as well as a link to a graph showing the history of scores for this test. There is also a link to a treeherder page showing the jobs in a pushlog format.

Maybe it's due to XDR script sizes or something? Is there a per-file breakdown? Not much I can do with just the raw numbers.
You can always hit subtests for any line in the alerts page linked above to get details on the individual tests. Though now that you mention that seems to be broken for installer size. :) I'll look into it. The only nugget of information I could get was for linux32, which shows this: https://treeherder.mozilla.org/perf.html#/comparesubtest?originalProject=mozilla-inbound&originalRevision=181336fdda6625d8ffa5e5764b817cc3da1f9659&newProject=mozilla-inbound&newRevision=bd702fa23037799ab4dd266d8a2b59d021f6cfa8&originalSignature=ba1be56522b3f8dc520262383b4e6afae13b72ad&newSignature=ba1be56522b3f8dc520262383b4e6afae13b72ad&framework=2 It looks like the size of libxul.so jumped by a bunch (about 100k), which might explain the bulk of this change?

Hi :jlongster, Not sure if you are right person for this? Can you help shed some light here or help find an owner for this bug?
I am not the right person for this. I do not work on SpiderMonkey or the related bug mentioned above at all.
I think we should just close this as wontfix. A few hundred k in the installer size isn't that big a deal, I filed the bug in case something jumped out against the original committer.
