Just pushed support in WPT for collecting memory stats at the end of a test: https://github.com/WPO-Foundation/webpagetest/commit/629f48ea5c57be57b50e1f97942c98dface593b2 Sample result: http://www.webpagetest.org/xmlResult/160212_3Z_12D1/ Specifically: browser_process_count - Number of browser processes browser_main_memory_kb - Full working set of the "main" browser process in KB (main for WPT is whatever is doing the network communications) browser_other_private_memory_kb - Sum of the private working sets for all other browser processes (in KB) browser_working_set_kb - Both working set numbers combined _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
