This is Scrutiny v4 checking a very large website. (Integrity 4 and Scrutiny 4 are now both available as release candidates)
The major change is to the engine. You can't see the speed that Integrity is tearing through this site but it's collected 33,000 links and checked 16,000 of them in about 15 mins. And hardly stressing the computer!
I'm dead chuffed with the improvement and also with Scrutiny's new application icon which reflects the fact that it can handle larger sites and process the data more quickly.
