I've spend the past weekend doing some comprehensive optimizations to ClojureScript, these can be seen here: https://github.com/clojure/clojurescript/compare/all-optimizations
With these optimizations operations are anywhere from 1.5X-5X faster depending on the operation and the JavaScript environment. These optimizations include: * respect boolean type hints on fns * remove CLJS truth tests if we can infer that an if's test expression is boolean - this works for common combinations of and/or - this removes nearly all truth tests from PersistentVector, big wins here and for other persistent data structures to come * multi-arity fns that are not used higher-order are now dispatched directly to the correct arity instead of using JS arguments - multi-arity protocol fns also benefit from this optimization * remove all truth tests from protocol dispatch fns Feedback & improvements appreciated. Please try this branch out and let us know if it works for you - especially interested if things are faster, slower or if the changes adversely affect your file sizes under advanced optimization.
