<pre wrap=""> I have exactly the same problem. I've investigated the loading of the page with the

Maybe this will help debugging this further?
After the initial load the future loads of that js will be cached and therefore much slower.
And after the cache expiry (typically the next workday) you have to wait for another 30
seconds to get the WYSIWYG editor back up again.

While this confirms that something is taking a long time to load, the
consistent 15 seconds on each request is quite odd, especially since
larger files take mere milliseconds to download.
Are you using JSMin? How is your RT configured, etc, etc.
If you can replicate these timings on issues.bestpractical.com it
would be interesting.

I have the following output from Chromium's network headers when
loading ckeditor.js. When refreshing the page (F5) this timeout of
15 seconds occurs. You see the Keep-Alive is set to timeout=15, what
does that mean?<br>
