It's been a long time since I looked at this, but as of a few years ago, the biggest noticeable performance detriment of comp or partial was likely to come if you pass enough args to hit a "& args" overload, which requires creating a fresh object array at each call, when the underlying function being called has a non-"& args" arity.
On one application I worked on, we preferred defining #(anonymous ...) functions to some uses of higher order functions to avoid excessive garbage-creation in some hot spots. This assumes you don't need primitive type-hint-level optimization. I wouldn't recommend sacrificing any clarity unless you've profiled and found a real issue. definition of partial: https://github.com/clojure/clojure/blob/master/src/clj/clojure/core.clj#L2614 definition of comp: https://github.com/clojure/clojure/blob/master/src/clj/clojure/core.clj#L2557 On Sun, Oct 20, 2019, 3:25 PM david hoyt <davidpaulh...@gmail.com> wrote: > Is there a performance benefit (or detriment) to creating partial > functions?
