There have been a few reports recently about the WordPress dashboard sometimes responding slowly. This was occurring for some of our OM4 WordPressMU client sites.

Occasionally a dashboard page load could take up to 15-30 seconds to complete. This is much longer than a typical page load, and could be quite frustrating.

The problem was caused by a bug in WordPress MU – we’ve applied a fix to our platform because it was so annoying but the problem is due to be fixed in the next version of WordPress MU (2.7.1) as well.

We’re always on the lookout for performance issues with our OM4 WordPress sites and fix them if they occur. So if you notice any problems, please let us know.
