===== Windows 8 | ===== Scroll - e10s and Windows 8 / 10 (Firefox) ===== | ||
* Performed by: aklotz, avih | * Performed by: aklotz, avih | ||
* Compare Firefox scrolling performance between Windows 8.1 / 10 and e10s modes, using different power modes, test pages, and tabs | |||
* Tested using the scroll-test bookmarklet from bug {{Bugzilla|894128}} ([https://bug894128.bmoattachments.org/attachment.cgi?id=776049 this]) | |||
* On each config, run the bookmarklet few times and register the result (average and stddev) of a single run which seems typical | |||
* Base configuration: | |||
** System: HP reference laptop, Windows 8.1 and Windows 10 - always connected to power. | |||
** Firefox Nightly 42 2015-08-02 with APZ disabled | |||
** Bookmarklet config: 7000 (ms scroll), 10 (pixels/step), 0 (don't ignore first frames) | |||
* Tested configurations: all the combinations of the following: | |||
** Page: facebook.com/llbean / twitter.com/Lord_Voldemort7 / Yahoo search results ("mozilla") | |||
** OS: Windows 8.1 / Windows 10 | |||
** Power mode: balanced / power saver | |||
** Active background tab (gmail while it reloads): Yes / No | |||
* Observations: | |||
** It's really hard to take/get consistent measurements while gmail loads in the bg, due to network latency, gmail load timing, etc. | |||
** Facebook scrolls worse than yahoo/twitter on most configs (except single tab + balanced where the system is fast enough and all pages reach ~60fps) | |||
** Power saver shows consistently worse results than balanced | |||
** No major differences between win8 and 10 across the board | |||
** No major differences between non-e10s and e10s | |||
** Single tab - no major differences between non-e10s/e10s/e10s-multi(3) | |||
** Gmail loading in bg - affects most* configurations badly | |||
*** Except e10s-multi(3) which improves performance on this case dramatically | |||
