browser is unresponsive when single page has large iframed ckEditor instances

[jignesh.dalwadi]

Hi, We are using CKEDITOR 4.4.8 (revision:ccd0038). In our application we have a page which have 222 iframed CKEditor instances. When we load this page in IE 11 and chrome, browsers responds very very slowly. In case of IE 11 we get alert like '.. not responding due to long running script.' for this page loading. When we traced browser log, we found multiple calls to contents.css. We noted that all these calls of contents.css are provided from cache by browser but the issue is CKEDITOR calls multiple times (in our case 222 times) to browser and that's making browser almost unresponsive. We have already referred ​https://dev.ckeditor.com/ticket/10425. Do you have any work around to prevent browser slowness when single page has such large iframed ckEditor instances?

Thanks.. Jignesh Dalwadi
