I experience a few seconds of jank when opening a google groups' group page such as mozilla.dev.platform. A gecko profiler profile for this is available here: http://people.mozilla.com/~bgirard/cleopatra/?report=bd345397daed044bf60792452d9c80edb9d4a235 My about:support has been attached as a text file.
I notice this on x64 Windows 7 on all Google Blogspot blogs that use widgets and default themes.

Here's a profile for opening the "my groups" page at google groups. http://people.mozilla.com/~bgirard/cleopatra/#report=d0d1a2602885fe296ab0d64c6c4be88e27415b2c Most of the jank period seems to be spent in an Evaluate String operation. Profile was recorded on an Intel E8500 based machine with win7 x64. 06/02 moz-central nightly win32 build. https://groups.google.com/forum/#!myforums

even opening the gmail page for the first time causes ~1-1.5 seconds jank. Profile : http://people.mozilla.com/~bgirard/cleopatra/#report=aad761f1529578c57c9fee68ce3ceb8b60288de3 IIRC this is already being tracked in another bug. Should be P1, IMO.

There is also quite a bit of jank when using the "u" keyboard shortcut to return to group page from a thread page. e.g. Go to the moz.dev.platform group: https://groups.google.com/forum/#!forum/mozilla.dev.platform Then enter the thread for "How does one debug uninitialized value usage from JavaScript (TB) ?". https://groups.google.com/forum/#!topic/mozilla.dev.platform/fEUHUse_qb8 Then press the "u" key to return to the moz.dev.platform group. I do not see this when using the same keyboard shortcut to return to my inbox in gmail for example. The operation also completes a lot more quickly in Chrome. The profile is here: http://people.mozilla.com/~bgirard/cleopatra/#report=a919bc7a8903d32c10c294240efef8f700e9cd9f Most of the jank time seems to be spent in the JS interpreter.

That profile was recorded on an Intel E8500 based machine running todays moz central nightly win32 build, on win7 x64.

http://people.mozilla.com/~bgirard/cleopatra/#report=c5caf961350d8ccb46dcd8825fc8bc741f023f85 In google groups, switching from "compact list view" to "standard view".

Can you still reproduce? https://groups.google.com/forum/#!topic/mozilla.dev.platform/fEUHUse_qb8 takes a long time to load. But I do not experience jank. This is with a current nightly and e10s enabled, heavily loaded with 400 tabs I also cannot reproduce related bug 924001, nor bug 802731

Looks like there is still a little bit of jank (like less than 500 ms), but it is much better.
