I'm having some perf issues with a huge form I'm dealing with. \r\nThe form has 83 fields (yeah.. I know.. but it is what it is) and typing on any input is impossible, as the input lags/hangs to the point where it becomes unusable.\r\nFor each key pressed, my component is rerendering. Is that the correct behavior?\r\n\r\nI tested with the redux-form demo website and it lags as well if you add enough fields to it:\r\n\r\n![mwwgfj1](https://cloud.githubusercontent.com/assets/941075/12243471/dc57edb8-b885-11e5-81fe-4c8f5fdaed39.gif)\r\n\r\nSee how the text appear in blocks of text, instead of one key after another. I captured this with 24fps, so it's not a gif issue.\r\n"},"comment":{"url":"https://api.github.com/repos/erikras/redux-form/issues/comments/184987275","html_url":"https://github.com/erikras/redux-form/issues/529#issuecomment-184987275","issue_url":"https://api.github.com/repos/erikras/redux-form/issues/529","id":184987275,"user":{"login":"steida","id":66249,"avatar_url":"https://avatars.githubusercontent.com/u/66249?v=3","gravatar_id":"","url":"https://api.github.com/users/steida","html_url":"https://github.com/steida","followers_url":"https://api.github.com/users/steida/followers","following_url":"https://api.github.com/users/steida/following{/other_user}","gists_url":"https://api.github.com/users/steida/gists{/gist_id}","starred_url":"https://api.github.com/users/steida/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/steida/subscriptions","organizations_url":"https://api.github.com/users/steida/orgs","repos_url":"https://api.github.com/users/steida/repos","events_url":"https://api.github.com/users/steida/events{/privacy}","received_events_url":"https://api.github.com/users/steida/received_events","type":"User","site_admin":false},"created_at":"2016-02-17T02:48:39Z","updated_at":"2016-02-17T02:48:39Z","body":"@davidkpiano Check Este implementation. The form state is updated only when model has been changed. By my own experiences there is no performance bottleneck."}}
