@pawandubey you could also switch to a non-blocking http client and swerve the extra threads e.g. https://github.com/dakrone/clj-http#async-http-request https://github.com/ztellman/aleph http://www.http-kit.org/

yes, if that were his only issue it would be simpler — but he also has file i/o, which complicates it a bit. {:async? true} for clj-http makes it async, but there’s the writing to consider

ah, good point @joshjones . a clojure wrapper for java nio would be nice
