I've been using Uglify2 in my project (https://github.com/MatAtBread/nodent) for around 18months, and like it a lot, however, it seems like Esprima have been working hard on performance and are now claiming to be 5x-10x quicker (see http://esprima.org/test/compare.html), at least on Chrome 41.\r\n\r\nMaybe related to https://github.com/mishoo/UglifyJS2/issues/636? Any info or comments on whether the benchmark is realistic and/or whether performance is considered an issue for Uglify2?\r\n\r\nAny feedback much appreciated"}}
