I wonder what types of controls they have over the data they cache. While caches are by nature "public", given suitable naming, unless you have a link, they are effectively private. > To understand the impact on overall performance I ran jpegtran over a set of 34,159 actual images from one of our caches.

That's a great question. Answer: a lot of control. In order to run the cache experiment Vlad had to file an access control ticket which I had to approve. He was given access to cached images from two dogfooding/guinea pig machines and was able to run his experiment on those machines. They are not machines through which we run 'normal' production traffic.
