From d327870d3fe663d3ca2b0b05829b900630a33e5a Mon Sep 17 00:00:00 2001 From: "eric@webkit.org" Date: Tue, 4 Oct 2011 00:13:01 +0000 Subject: [PATCH] Add a microbenchmark for a full-page render of the HTML5 spec https://bugs.webkit.org/show_bug.cgi?id=69285 Reviewed by Adam Barth. This was designed to be a test for https://bugs.webkit.org/show_bug.cgi?id=68944 But it seems that by far our dominating cost for the HTML5 benchmark is time spent laying out lines (which isn't actually that surprising). I'm adding the performance test for posterity. * Parser/html-parser.html: - Removed use of "about:blank" which abarth says is a no-op. Made comment more accurate. * Parser/html5-full-render.html: Copied from PerformanceTests/Parser/html-parser.html. git-svn-id: http://svn.webkit.org/repository/webkit/trunk@96559 268f45cc-cd09-0410-ab3c-d52691b4dbfc --- PerformanceTests/ChangeLog | 17 +++++++++++++++++ PerformanceTests/Parser/html-parser.html | 3 +-- PerformanceTests/Parser/html5-full-render.html | 20 ++++++++++++++++++++ 3 files changed, 38 insertions(+), 2 deletions(-) create mode 100644 PerformanceTests/Parser/html5-full-render.html diff --git a/PerformanceTests/ChangeLog b/PerformanceTests/ChangeLog index 3eec52e..9e8fbe6 100644 --- a/PerformanceTests/ChangeLog +++ b/PerformanceTests/ChangeLog @@ -1,5 +1,22 @@ 2011-10-03 Eric Seidel + Add a microbenchmark for a full-page render of the HTML5 spec + https://bugs.webkit.org/show_bug.cgi?id=69285 + + Reviewed by Adam Barth. + + This was designed to be a test for https://bugs.webkit.org/show_bug.cgi?id=68944 + But it seems that by far our dominating cost for the HTML5 benchmark is + time spent laying out lines (which isn't actually that surprising). + + I'm adding the performance test for posterity. + + * Parser/html-parser.html: + - Removed use of "about:blank" which abarth says is a no-op.
