We have just finished setting up our new server and have an issue where loading pages after operations such as adding subdomains, email accounts etc. is slow?
When a subdomain is added, the page shows as loading, and takes around 10 minutes to load, but if you stop it loading, the subdomain still seems to be created. I don't think it's harware related as the server load is normally about 0.05 and there are only about 10-15 accounts on the server.
Any ideas would be great!

We've managed to find what the problem for us was, our backup DNS server was down, and the cPanel sever was then probally trying to copy records accross, but obviously it wasn't working.
Hopefully this can help anyone else who seems to have this issue :)
