Once the buffer is open, I can't see any slowdown and flycheck operates normally. When disabling Flycheck, opening the buffer is instantaneous.\r\n\r\nI'm not sure what changes between the last release and the last build on MELPA, if it's how flycheck runs when opening a buffer or if it has to do with how eslint is run.\r\n\r\nI tried this with a clean (no config file loaded) Emacs v 25.1, with the following\r\n\r\n```elisp\r\n(require 'package)\r\n(add-to-list 'package-archives\r\n             '(\"MELPA Stable\" . \"http://melpa.org/packages/\") t)\r\n(package-initialize)\r\n(package-refresh-contents)\r\n\r\n(package-install 'flycheck)\r\n\r\n(global-flycheck-mode)\r\n```\r\nInstalling Flycheck 29 instead fixes the issue."},"comment":{"url":"https://api.github.com/repos/flycheck/flycheck/issues/comments/254508593","html_url":"https://github.com/flycheck/flycheck/issues/1129#issuecomment-254508593","issue_url":"https://api.github.com/repos/flycheck/flycheck/issues/1129","id":254508593,"user":{"login":"lunaryorn","id":224922,"avatar_url":"https://avatars.githubusercontent.com/u/224922?v=3","gravatar_id":"","url":"https://api.github.com/users/lunaryorn","html_url":"https://github.com/lunaryorn","followers_url":"https://api.github.com/users/lunaryorn/followers","following_url":"https://api.github.com/users/lunaryorn/following{/other_user}","gists_url":"https://api.github.com/users/lunaryorn/gists{/gist_id}","starred_url":"https://api.github.com/users/lunaryorn/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/lunaryorn/subscriptions","organizations_url":"https://api.github.com/users/lunaryorn/orgs","repos_url":"https://api.github.com/users/lunaryorn/repos","events_url":"https://api.github.com/users/lunaryorn/events{/privacy}","received_events_url":"https://api.github.com/users/lunaryorn/received_events","type":"User","site_admin":false},"created_at":"2016-10-18T13:33:10Z","updated_at":"2016-10-18T13:33:10Z","body":"I kind of like the idea :+1: but I still see a couple of open questions… mind if you open a pull request so that we can discuss in detail?"}}
