With the help of criu [1], I can get clojure's startup time on jdk 1.8 down to around 300 - 350 ms [2] This could be considered cheating, because it only works on linux with `CONFIG_CHECKPOINT_RESTORE=y`, but it also demonstrates, what can be achieved with kernel support. [1] https://criu.org/

Yep, I meant the thing, `vector` is doing. Thanks! 2015-08-13 13:36 GMT+02:00 Amith George strider...@gmail.com: Maybe you meant to use `vector` instead of `vec`? `vec` doesn't accept variable args. Hence my original question. On Thursday, 13 August 2015 16:24:43 UTC+5:30, Herwig Hochleitner

Re: no set-car! in clojure

You could define your own cons type, like Bodil Stokke did for her microkanren https://github.com/bodil/microkanrens/blob/77dbdc34cde580e26765138102cbdabbfad85b9d/mk.clj#L13 If you mark its fields with ^:volatile-mutable, you can call (set! (.-a lst) new-car) on a cons instance. cheers -- You

2015-06-24 18:19 GMT+02:00 Ben Wolfson wolf...@gmail.com: I meant a difference in speed. A var-root fetch is a volatile read, which can have several adverse performance effects. Most importantly, it hinders inlining, since the JIT has to place a guard for every inlining site of a volatile
