Consistent hashing — wow! :)

“One thing we pulled out of our G4 setup was a RAID card. We'd experimented with hardware RAID but found we got more performance addressing each disk individually and using consistent hashing in the algorithm to spread files across disks. Specifically, we saw a 50% performance benefit addressing disks directly rather than going through the G3 hardware RAID. The additional reliability of RAID isn't as important for our application as we can always go fetch a copy of the original object from our customer's origin server if necessary.”

And yet, they still can't tell us which of PandaWhale's assets are most popular.

A little less rocket science, and a little more practical tools please, CloudFlare.
