About:Snappy

[_Alexander]

Oh and here is me doing two things on my netbook (very good DX10 GPU!!!),
a. Scrolling up and down Neowin.net - adblock plus enabled
b. Switching between YouTube tab and about:jank tab

Code: Select all

records samples that occured in during periods when we did not service the event loop for more than > 100 ms.
NOTE: about:jank doesn't interact well with the Gecko Profiler Addon
about:jank results (2632 samples)

Should I report this to Bug 721273?!

Sounds like something to report - especially with the about:jank data.

Never mind, I was late..

You're late Zlip, see the previous page.

I see people are using it already but I didn't see the new version mentioned.

Does somebody have a link to explain about:jank and its interest in improving responsiveness?

Decode ::Draw()'n images before other images just landed today.
Great for switching tabs with large number of images . Snappy is showing its true colors

Great! I am pretty sure the previous version i have installed was 0.1. The AMO one is 0.4!

gfx::DrawThebesLayer is the Gecko Layers API. All of the interfaces ties into it. Its probably something to do with Cairo. Maybe a test with Azure-Thebes on is worth a look.

Also, MSVC2010 is a go!

The results are in:

"Our data says half of one percent of our Windows users are on these
older systems and that a disproportionate number of them are on Firefox
3.6."

With so many on 3.6, a lot aren't interested in upgrading anyhow. Asa's
take is that we are ok to be forward looking on the release train. This
seems good since we'll get performance improvements for 99.5% of our
Windows users.

With that in mind, I suggest we turn on VS2010 post Tuesday (next
uplift).

We should get a bug going to notify users affected that support will be
ending.

Thanks,

I guess for the first year we can use the first ESR build.

And that means a green light for 64-bit?
Sorry for ot.
