The London Clojurians are happy to present: Title: Java Interop Performance Speaker: Alex Miller Alex Miller ( insideclojure.org ) will be presenting: "Java Interop Performance" Java interop is a common area of Clojure performance issues. In this talk we'll look at the two most important issues - reflection and boxed math. You will learn how to detect these problems (and develop an intuition for when they will happen), and how to fix them with type hints. Alex Miller is part of the Clojure core team working at Nubank and coauthor of Programming Clojure and Clojure Applied. He is also the creator of the Strange Loop, Clojure/west, and Lambda Jam conferences and one of the organizers of the Clojure/conj conference.
