John beat me to the post. Popfly is now running on top of Cacheman and we're seeing anywhere between a 2x-6x perf improvement depending on the mashup you're running. This is also the first time Cacheman has been put to real production usage and so far, it has been handling all of Popfly's traffic without breaking a sweat.

This has to be the first time one of my pet projects has proven remotely useful so I'm pretty pleased :-)
