• Regressed, see bug 1255175

talos tp5o_scroll

• e10s comparison validated: kats
• Current e10s diff: worse except linux
  • Linux: 17% better
  • All Windows and OS X: 45-110% worse
• bug 1179735 - tp5o_scroll regression on windows compared to non-e10s
• Note: reflects synchronous scroll only, so meaningless where APZ kicks in. Currently APZ handles only mouse wheel, so the test currently reflects autoscroll/arrows/page-up-down/etc.
• kats comments on apz and this test

talos tscrollx

• e10s comparison validated: kats
• Current e10s diff: mixed
  • Linux: 30% better
  • OS X: 17% better
  • Windows 8: 7% better
  • Windows 7: 7% worse
  • Windows XP: 50% worse
• bug 1249976 - tscrollx regressed 6% with e10s on December 25th
• bug 1174772 - 2.9% win7 tscrollx regression on e10s only
• Note: reflects synchronous scroll only, so meaningless where APZ kicks in. Currently APZ handles only mouse wheel, so the test currently reflects autoscroll/arrows/page-up-down/etc.
• Note: tscrollx improved with e10s + no apz 6%-40% so this regression appears to be apz related.
