just wondering if the following bug would cause significant faster startups and called “snappy” too?

Hi Taras, I have been noticing (often severe) jank on a lot of google services’ pages.

The worst is when opening many blogspot sites (it will hang the browser). Most time seems to be spent in the YARR interpreter. This has been profiled (with the gecko profiler) here and reported here:

https://bugzilla.mozilla.org/show_bug.cgi?id=792797

Another user reported a bug on it (with profile) here:

https://bugzilla.mozilla.org/show_bug.cgi?id=791627

Have also profiled and reported jank when opening a google groups page:

A mozilla dev recently reported several seconds of jank when opening a google doc:

Cheers,

Tim.

@JC_Yang I didn’t meant to say Snappy and E10 have the same purpose. I may have not have expressed me clearly.
I just remember Tara was working on other subjects before Snappy –mainly E10 at that time– and wondered how he expects his work to evolve with Snappy.
Is it expected to focuse mainly on Snappy for another 3, 6 months, one year? And how Snappy will be handled when the main efforts are complete and the biggest part of his work shifts to other activities.
But maybe Snappy’s birthday will be a more appropriate time to draw this wider picture of the project.

Hi Taras, thanks for your response. Which Add-on are you referring to? One of these?

https://addons.mozilla.org/en-US/firefox/addon/xul-profiler-by-yoono/

https://addons.mozilla.org/en-us/firefox/addon/memory-profiler/

Neither of those are marked for compatibility with the version of Aurora I’m currently using. Is it safe to try one of them by dismissing the compatibility check?

@kamulos, if you cannot find a bug, file one. the worst thing that can happen is the bug will be marked a duplicate of another.

Is there work being done on Box Shadows? This seems to be the No.1 reason for slow drawing for me. I occasionally record a profile when scrolling on the page stutters and almost always a box shadow is the culprit (like 718453).

I never found a bug for this… is there one?

No new updates from the dlbi bug (539356) since 28 aug.
Is it on hold ?

@pd

Install profiler addon, record a profile, post link to it in a bug. Might be something other than cycle collection, gc causing this problem.
