Typing very slow in TINY MCE editor

I have large data of content (newsletter) and I have added in Tiny Mce Editor. Contents looks fine but when I start typing (adding more content) it types very slow and I have to wait until it's done printing the character.

The issue is with large contents only not with small content.

You can check below demo link to test the above case. Paste the large content it source code and try to type in Tiny Mce editor not in source code.

Solution

i faced similar issue. My problem was that in tinymce.init i had a function for update textarea:

setup: function (editor) {
        editor.on('change', function () {
            tinymce.triggerSave();
        });
    }

Problem was that the function update textarea with every change, with every key press or color change. More content, more slower.

My solution here was simple, delete triggerSave from tinyMCE init and call tinymce.triggerSave() right before submitting form via submitting button:

<button type="submit" name="btn-addpost" onclick="tinyMCE.triggerSave();"><span class="glyphicon glyphicon-send"></span>&nbsp; Add Post</button>

Maybe you have similar problem.

I hope this will be in any way helpfull for you.
