Hi Marko,

I've just upgraded an existing site to 4.4 but I do not have the problem of slowness you encounter. I think you should try to load the site in Firefox with Firebug enabled and look at the Network tab to see what is so long. In fact, the loading of this part is done in several step :

1. the page is loaded
2. when the document is ready, the YUI loader component loads several CSS and JS files. Depending on your configuration, those files are fetched from the eZ Publish site itself or from a remote CDN
3. then a YUI component builds the table by loading asynchronously a json document

Btw, there should be a GIF spinner ou a simple message telling to the user that something is loading.

Cheers

OK, I have investigated further. It seems like the browsers don't cache properly the JS and image files. So they are loaded again on loading of the page. An that's where the delay occurs.

I have measured the loading of the subitems and inspected the traffic with Fiddler and here are the results:

Note that only Opera caches everything and works OK on next loading of the page.

I have measured the time from when the "Subitems" text is displayed, until the table with subitems is displayed. Here are the conditions for each test:
first time - all the cache cleared and page loaded
second time - typing the URL again in the address bar after first time
after refresh - hitting the browser's refresh button after the second time
I have checked out with Fiddler and all the static items (JS, CSS, images) have the cache headers properly set, so that they get cached:

Last-Modified: Tue, 28 Dec 2010 08:57:40 GMT
Cache-Control: max-age=604800, must-revalidate
Expires: Mon, 15 Nov 2010 12:49:47 GMT

But as we can see the browsers still refuse to cache them.

This is very strange because all my browsers are installed with the default installation and I didn't change their cache settings.

Anybody has any clue what could be the problem?

P.S. It seems to me that a lot of potential problems could come from this ajax approach of fetching subitems...

Hi

I got similar problems. I thought it was may be due by the fact I was using FF 4 on Mac, then I've tested on another browser on PC, problem is the same.

Furthermore, I have another issue: The sensitive context menu on t he "tool icon" is not displayed, while the one in left tree_menu does work.

NO

--EDIT--

The second point seems to be a bug which has been corrected since (issue 017355 )
