Re: lein uberjar much faster as lein run
I recall reading that `lein run` uses JVM options optimised for startup time, not performance - as it's intended for use in development, not production.

Somebody with actual knowledge of what's under the hood will undoubtedly be able to say more (and maybe correct me :-), but I've been led to believe that if you want things to run fast (at the expense of possibly longer startup time) with lein run then you actually want to use lein with-profile production run.

That gives: 1 threads took 11811 milliseconds 2 threads took6015 milliseconds 4 threads took3155 milliseconds 6 threads took2567 milliseconds 7 threads took2356 milliseconds 8 threads took2218 milliseconds So that is comparable to uberjar. I will use this in the future. Thanks. -- Cecil Westerhof -- You received this message because you are subscribed to the Google Groups Clojure group.

https://github.com/technomancy/leiningen/blob/master/leiningen-core/src/leiningen/core/project.clj#L415 TieredCompilation is the relevant one.

Re: lein uberjar much faster as lein run
By default, lein run will use tiered compilation, which starts faster, but is not as fast. https://github.com/technomancy/leiningen/wiki/Faster On Tuesday, April 22, 2014 9:01:34 AM UTC-5, Jony Hudson wrote: I recall reading that `lein run` uses JVM options optimised for startup time, not performance - as it's intended for use in development, not production.
