Hi all,
I'm trying to repack an existing Java lib with native dependecies and

native parts are stored in a lein compatible layout. In the past (lein 1.x
era) I had no problems with that, but I just can't get this to work

Hi,
In reducer-reduce you iterate twice over the values compared to the java
version, once in map (just to call .get), then in reduce.
There are other issues probably, but this is one of the obvious ones.

The reduce is not a big problem, 'cause after all it'll only process 88

It's the mapper function that cost much more than the java version. One

Hi,
I believe I can confirm that it's the startup time issue.
I set mapred.job.reuse.jvm.num.tasks=-1 and the overall time is approximate

this doesn't quite make sense: Since Clojure is well-known for its

All the concurrency features built in to clojure are concerned with things
