That's fine, but it's exactly the opposite of the attitude expressed in the post. "The ratio of bytes loaded to load time should be very close to the I/O throughput of the machine." How do you think the bytes served for a few hundred requests a minute compares to the theoretical I/O throughput of the relevant machines? And because no one can see my tongue in my cheek across the internet, I'll be explicit that I'm sure he is a user of his publishing environment, not it's author, and so it's fair to view this as just another symptom of the problem he's discussing.
