I did something similar in Javascript. My implementation uses the Runge-Kutta algorithm, that is more stable. My GUI does not allow planet creation, but it shows several stable configurations, including the 13 recently found three body planar orbit configurations.
I have a very similar problem and end up writing a python script that copies the files to cassandra and Nginx + Lua to serve them using lua-resty-cassandra. The read/write throughput is still not as good as I was expecting though.
It would be interesting to see the same data broken down by year. Lua, Clojure, and Go are at about the same position, but I wonder which one is gaining traction. Probably Go.
It's hard to believe that JavaScript and Transact-SQL have more or less the same popularity (1.569% against 1.559%). That's why I don't care about this index anymore.
Ilya Grigorika, the presentation author, has also written a book called High Performance Browser Network that I highly recommend if you are interested on the subject.
With OpenCV you can also do face detection and feature recognition for smarter crops. Thumbor does that and is used in a large scale at globo.com: https://github.com/globocom/thumbor.
