I too have a very slow edit page. However, I am NOT using repeater plugin on this page. I am using the flexible content though. Also, it gets worse and worse the more flexible content I add.
BTW, I do have the repeater plugin installed. Also, i’m on WordPress 3.8

Looks like there is a bunch of Garbage Collection that occurs during my 7 second freeze. Here is a screenshot: https://www.dropbox.com/s/43esgobg2jmzquq/Screenshot%202014-02-25%2009.29.37.png
Here is the timeline output for the event:

So what I did was click on “add new layout” for my flexible content, then choose one from the list and then it freezes. I also get lags in scrolling and just general stuff. Anything else I can do to help,just let me know.
