Just for the record, I coded this analysis up here: https://gist.github.com/matthew-brett/9cb5274f7451a3eb8fc0 SSE2 apparently now at about one percent: 20120102-pub-crashdata.csv.gz: 4.53 20120401-pub-crashdata.csv.gz: 4.24 20120701-pub-crashdata.csv.gz: 2.77 20121001-pub-crashdata.csv.gz: 2.83 20130101-pub-crashdata.csv.gz: 2.66 20130401-pub-crashdata.csv.gz: 2.59 20130701-pub-crashdata.csv.gz: 2.20 20131001-pub-crashdata.csv.gz: 1.92 20140101-pub-crashdata.csv.gz: 1.86 20140401-pub-crashdata.csv.gz: 1.12 Cheers, Matthew _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
