MediaWiki extension: HORRIBLY slow load times

Hi there, I just installed FCKeditor as a MediaWiki extension on Apache 2.2.9, PHP 5.2.6 and MediaWiki 1.13.0rc1. I compiled the extension from SVN and then installed the latest stable version of FCKeditor. It works, but depending on the browser the editor takes a very very long time to initialise.

The primary browser we intend to support with this wiki is Firefox, and unfortunately Firefox 3 has the worst times. It takes roughly 10+ seconds to load up the editor on my wiki. I'm not sure why this is happening because Firefox 3 loads the FCKeditor fairly quickly on the FCKeditor wiki here: http://mediawiki.fckeditor.net/index.ph ... ction=edit

On my wiki, Firefox rapidly switches between "Trasferring data from domain.org" and "Waiting for domain.org" really quickly in the bottom left corner of the browser window. For heavy editing, such a long load time is unacceptable.

Is there something I can do to improve performance? Could it be a bug in the revision of the extension I checked out? Another configuration option I should try and change? How can I debug this?

Thanks

Use a debugging HTTP proxy to see what's going on with your traffic. Here's a good one you can use: http://www.charlesproxy.com/.

Re: MediaWiki extension: HORRIBLY slow load times

All I had to do was update the fckeditor (not the extension). Must have gotten a rotten nightly build the first time.

It was annoying while it lasted, but fortunately it's gone.

Couldn't find any good HTTP debuggers for GNU+Linux. Are there any Free Software cross-platform ones?

Re: MediaWiki extension: HORRIBLY slow load times

hello,

I have the same problem. I updated the FCK editor version from 2.5.1 tot 2.6.3 but still the loading costs about
10 seconds. Looks like many http requests...
checkout http://www.leerwiki.nl

is this normal?
regards

Re: HORRIBLY slow load times with Firefox 3

We just recently switched our site from TinyMCE to FCKeditor 2.6.4, and we are seeing extremely slow load times in Firefox 3. The load times are so slow that occasionally we get an error message stating that "A script on this page may be busy, or may have stopped responding. You can stop the script now, or you can continue to see if the script will complete."

The problems are especially bad on pages that have 2 or 3 text entry fields where the editor loads. The refresh/load/stop buttons on the browser navigation bar flicker probably 15 or 20 times as the javascript continually sends requests back to the server. We don't see this problem in Internet Explorer, although there are times I have seen in IE where the page stops loading when it gets to the rich text editor location, refreshes the *entire* page and starts loading again, and is then successful on the second attempt.

Any suggestions on how we might fix these problems? Is this an issue with core code or something else? We are running Drupal 5 as our core content management system.
