Build time varies but ballpark should be around 200-300ms\n+for small to middle size applications and up to 1 second for large size applications.","path":"PERF_GUIDE.md","position":19,"original_position":19,"commit_id":"a5c0b7d8b9e82ed159701ec8599ee55ab9e0a6a7","original_commit_id":"a5c0b7d8b9e82ed159701ec8599ee55ab9e0a6a7","user":{"login":"MiguelMadero","id":47388,"avatar_url":"https://avatars.githubusercontent.com/u/47388?v=3","gravatar_id":"","url":"https://api.github.com/users/MiguelMadero","html_url":"https://github.com/MiguelMadero","followers_url":"https://api.github.com/users/MiguelMadero/followers","following_url":"https://api.github.com/users/MiguelMadero/following{/other_user}","gists_url":"https://api.github.com/users/MiguelMadero/gists{/gist_id}","starred_url":"https://api.github.com/users/MiguelMadero/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/MiguelMadero/subscriptions","organizations_url":"https://api.github.com/users/MiguelMadero/orgs","repos_url":"https://api.github.com/users/MiguelMadero/repos","events_url":"https://api.github.com/users/MiguelMadero/events{/privacy}","received_events_url":"https://api.github.com/users/MiguelMadero/received_events","type":"User","site_admin":false},"body":"what's considered a large application?
