One correction, however, is that in my first test I did test only against a single object of a fixed size but in the second test I had a script to generate random URLs that all point to files of different sizes. The script allows me to specify how many results, so I could easily generate 10,000,000 random URLs. Within this list there are (very) likely to be duplicate URLs which is similar to a production environment – but certainly not identical.

The script can be modified to be more or less random, but on average, most of our pages fall within the 25K to 35K range, so I tried to keep my tests within that range.

I should have said somewhere in my posts that while my results are indicative of the performance of both options in general, they are tailored to my needs. Do your own tests that correlate to needs of your own business if you want to get usable data for yourself.
