After a lot of struggling (is Angular the problem? Is this, that, or the other dependecy a problem?), we've found that Angular Material framework is simply slow in IE. In comparison, [LumX](http://ui.lumapps.com/) (a different Material Design + Angular framework) works fine in IE10/11.\r\n\r\n## Plnkr Demo of the Problem\r\nTo demonstrate the problem, I implemented a simple page with a Toolbar and list of Items in both Angular Material and LumX. They both perform equally well in Chrome, but ng-material is **much** slower in IE.\r\n\r\n### Performance Comparison\r\nTo test performance, I did the following:\r\n * Entered `900` in input box and submit (click `Add People` or hit Enter key)\r\n * Visually stop-watch the time from submission to the `(xxxx)` number updating\r\n\r\nPlnkr | Chrome | IE11\r\n---|---:|---:\r\n[ng-material demo](http://embed.plnkr.co/HtOJPtzfZFlvWAlCt58n/preview) | ~1s | ~8s\r\n[lumx demo](http://embed.plnkr.co/MGDRYEtyQWmULckRVh8y/preview) | <1s | ~1s\r\n\r\n### Versions Used\r\nLaptop: `Win7 64-bit, 16gb RAM, Core i7`\r\nChrome version: `Version 40.0.2214.115 m`\r\nIE11 version: `11.0.9600.17633`\r\n\r\nWhile I'd prefer to use Angular Material going forward, this performance difference in IE10/11 is a deal breaker for our product. Any help or insight into this issue is much appreciated!\r\n\r\n**PS:** I've also noticed in IE that when the ng-material demo page regains focus (e.g. click a different window then click back in), the page seems stuck and it often takes a while to scroll."},"comment":{"url":"https://api.github.com/repos/angular/material/issues/comments/128484395","html_url":"https://github.com/angular/material/issues/1771#issuecomment-128484395","issue_url":"https://api.github.com/repos/angular/material/issues/1771","id":128484395,"user":{"login":"ThomasBurleson","id":210413,"avatar_url":"https://avatars.githubusercontent.com/u/210413?v=3","gravatar_id":"","url":"https://api.github.com/users/ThomasBurleson","html_url":"https://github.com/ThomasBurleson","followers_url":"https://api.github.com/users/ThomasBurleson/followers","following_url":"https://api.github.com/users/ThomasBurleson/following{/other_user}","gists_url":"https://api.github.com/users/ThomasBurleson/gists{/gist_id}","starred_url":"https://api.github.com/users/ThomasBurleson/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ThomasBurleson/subscriptions","organizations_url":"https://api.github.com/users/ThomasBurleson/orgs","repos_url":"https://api.github.com/users/ThomasBurleson/repos","events_url":"https://api.github.com/users/ThomasBurleson/events{/privacy}","received_events_url":"https://api.github.com/users/ThomasBurleson/received_events","type":"User","site_admin":false},"created_at":"2015-08-06T19:46:56Z","updated_at":"2015-08-06T19:46:56Z","body":"*  Animation performances have been improved\r\n*  Tab performance has been significantly improved.\r\n*  SideNav and Ripple perf improvements are in-progress and scheduled for 0.11\r\n\r\n"}}
