The breadth benchmarks show a slight improvement."},"comment":{"url":"https://api.github.com/repos/nodejs/node/issues/comments/171832428","html_url":"https://github.com/nodejs/node/pull/4169#issuecomment-171832428","issue_url":"https://api.github.com/repos/nodejs/node/issues/4169","id":171832428,"user":{"login":"jasnell","id":439929,"avatar_url":"https://avatars.githubusercontent.com/u/439929?v=3","gravatar_id":"","url":"https://api.github.com/users/jasnell","html_url":"https://github.com/jasnell","followers_url":"https://api.github.com/users/jasnell/followers","following_url":"https://api.github.com/users/jasnell/following{/other_user}","gists_url":"https://api.github.com/users/jasnell/gists{/gist_id}","starred_url":"https://api.github.com/users/jasnell/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/jasnell/subscriptions","organizations_url":"https://api.github.com/users/jasnell/orgs","repos_url":"https://api.github.com/users/jasnell/repos","events_url":"https://api.github.com/users/jasnell/events{/privacy}","received_events_url":"https://api.github.com/users/jasnell/received_events","type":"User","site_admin":false},"created_at":"2016-01-15T00:55:59Z","updated_at":"2016-01-15T00:55:59Z","body":"@mscdex ... ping :-)"}}
