+
+ Add performance tests for DOM attribute getters and setters
+ https://bugs.webkit.org/show_bug.cgi?id=79208
+
+ Reviewed by Ryosuke Niwa.
+
+ This patch adds performance micro-benchmarks for DOM attribute
+ getters and setters. We selected DOM attributes from HTMLElement,
+ Element and Node which will most impact on the DOM performance
+ in the real Web and which have different call-paths from another
+ DOM attribute.
+
+ The perf test result in my local Chromium/Linux environment is as follows:
+ median= 14967.0 ms, stdev= 85.2385476178 ms, min= 14861.0 ms, max= 15155.0 ms
+
+ If we run the test with DumpRenderTree, we can get the following test results:
