Andrus,
Great idea! I think this could really help those who have an interest in optimizing performance.
Until then, what simple hooks could I add in myself to give me some visibility? (For example, I learned a bit about what triggers a fault by inserting some simple logging into the constructor of one of my data objects.)
Thanks
Joe
