Optimize pageload time/ TinyMCEComments (elephant)javascript

I added the TinyMCEComments plugin to let my readers comments using a WYSIWYG editor. But it delays pageloading time a lot. Since the script hooks into the comments form, everything loading after that form get delayed. That is my sidebar and footer.

Somehow it must be possible to tell the javascript to wait initializing the TinyMCE textarea untill the rest of the page is loaded. But how? Tried googling for settings for TinyMCE init() but can’t find anything that does what I want.

Any thoughts?
