@Sebastian It helps users if you add a readmefirst.txt file in the zip and explain that scripts need to run in a certain order. Or at least name the script files like 01...sql, 02....sql. It gives a hint that the scripts have an order to them.

Do you still have the issues with the site? We have a brand new site built in 7.1.2 and upgraded to 7.2.2 that has a serious issue when using the Advanced mode of the Friendly URL provider. After *a lot* of work to diagnose, we have found that

A simple way to check is to toggle the format of the Friendly URL provider in the web.config eg
<add name="DNNFriendlyUrl" type="DotNetNuke.Services.Url.FriendlyUrl.DNNFriendlyUrlProvider, DotNetNuke.HttpModules" includePageName="true" regexMatch="a-zA-Z0-9 _-" urlFormat="advanced"/> 
to
<add name="DNNFriendlyUrl" type="DotNetNuke.Services.Url.FriendlyUrl.DNNFriendlyUrlProvider, DotNetNuke.HttpModules" includePageName="true" regexMatch="a-zA-Z0-9 _-" urlFormat="HumanFriendly"/> 

When we did that it stopped sucking up the CPU. Have I found the fix? No, but I will post to here http://www.dnnsoftware.com/forums/forumid/108/threadid/499879/scope/posts if I find it, so if it does turn out that the Friendly URL provider is your problem it might be worth subscribing to that thread.
