​UI Jank Task Force Status Update

Last meeting until 2010.

*Status*

Carlos

   -
   Keep trying to build PGO.  Trying to build just a part of Chrome
(instrument just the ‘browser’ project) to get around the problem.

Chase

   -
   Tab switching tests problem resolved; re-enabled.  Cause is unclear
(interactive perf), bug filed.
   - Patch for reference build for tab switching tests in the works, will
   send to John.

John

   - Fixing the whole browser hang with Target’s flyer site.  Turned out to
   be an evangelism issue -- reported upstream.

Tony

   - Profiling renderer startup; most slowness is when renderer
   is waiting from the browser.  Not much to be done here.
   -
   Will try to move the visited database loading on the file thread.
(Will still block UI thread if it takes a long time to load)
      - Writes may be on IO thread, will look into moving them too.

Evan

   - Looking at tabstrip on Linux, found an improvement in tab-dragging.
   - Working on extensions, bugs.
