Engineer on finagle, used to work at tumblr when we started running into problems with finagle. In large part it was because we didn't understand how it worked, and were doing things like reinventing different pieces of finagle, like load balancing and service discovery.

I think saying colossus is "significantly better performing" is a bit of a stretch, although I haven't seen it in the past year, I think the main win was that you called epoll faster than netty, which I think was because you were using a faster timer. What are the performance comparisons you've done recently?
