Details
Cerberus has detected distribution changes on the 30th of August for the following histograms (see http://vitillo.github.io/cerberus/dashboard/): CYCLE_COLLECTOR CYCLE_COLLECTOR_VISITED_REF_COUNTED CYCLE_COLLECTOR_VISITED_GCED CYCLE_COLLECTOR_MAX_PAUSE CYCLE_COLLECTOR_FULL To me it seems like a possible regression of some kind.

(In reply to Olli Pettay [:smaug] from comment #1) > I think this is bug 1061202. Yeah, that would definitely do it. GHOST_WINDOWS probably also regressed.

So was there a corresponding improvement notification after the fix in bug 1061202 landed (4 days ago)? Or is it too early for that?

It's too early to tell, alerts have a one week delay.

As discussed on #perf, a manual check of the histograms confirms that the regression has been fixed.

Thanks for filing this. It is cool that telemetry noticed this. I need to get around to signing up for the mailing list.

It's super cool that we caught this.

It's also nice that we already knew what the cause was, otherwise there would have been a lot of head-scratching.
