Looks like your image fields have hardcoded ~/media in the raw values. that's most likely what messes things up.
We fixed this in one of the later versions.
You can probably fun a cleanup script on your content tree and fix this up. email me if you need the details.

Hey Alex--one important point about step 4. If you've already added items to the media library using the tilde (~), then change to something like a hyphen (-), we found admin users were no longer able to access existing media items via the content editor--they were getting "unauthorized access" errors. So we've changed back to the tilde, and access has been restored. Weird.

Thanks,

Arthur

Sumith,

Not more than 100 items per level is a common recommendation.

My test was not showing the correct improvements, a new run showed 0.5 better on Win2k8 and 0.2 on Win7. Still good for a small change like that :)

Ok, did a test of this in point 4 and with 10.000 HTTP GETs to some image in the media library I saw a performance improvement of x 8! And your right, it's only on Win2k8 you see this kind of improvement, on Win7 it's only x 0.5. May I suggest that Sitecore change ~ to - as the default, and also for all other handlers like the icon handler etc. :)

hehe, well I like numbers behind a statment like that - Especially when the setting is the default one :) But good find anyways!

Hi Per,

Wait...you don't trust me after all these years? :-)))

But seriously, nothing official at this point (hence a blog post), but our numerous load testing exercises with the customers show that this little change has dramatic difference on performance. Ability to change this prefix came in after we discovered this.

But you bring up a good point, you need to see the numbers. Hope I can get to it at some point.
