You may not have noticed but Popfly just got updated. It wasn’t one of those “check out all the new bells and whistles” kind of updates, though – it was one of those “behind-the-scenes” kind of updates instead. So what did they do? Besides fixing a few bugs, Popfly got an improved caching system. What this means is that they’ve made some changes to Popfly to take better advantage of the browser cache which leads to anywhere from 2 to 6 times better performance when you load up an existing mashup! Nice work, guys.
