That's it! Thanks so much for the help! In what cases is a function
turned into a RestFn? variadic clojure or vararg java? I was confused
about how clojure is turned into java, but things are a little clearer now.
(make-array) uses java.lang.reflect.Array.newInstance, which is bad as
well.
Offhand it looks like the only RestFn you call from filter-link is
clojure.core/format. Have you tried replacing that with something like this?
(String/format (.get link 1) (doto (make-array String 1) (aset 0 (.get link
2)))
I'm not suggesting that's idiomatic, but if it addresses the issue then

Let's try this again. Maybe the question is what is the most performant
way to consume a native java collection (List, array, or other) in clojure?
What I've tried so far hits clojure-imposed performance issues. How do I
get to near-java performance? I'm trying to create a polemic for clojur

Start by providing a snippet of your code and profiling.
Most likely you are hitting either boxing or extra method calls that are
not obvious from the code.
But nobody can tell if that's really the case, esp. without seeing the
actua
I'm working on a small clojure program which pulls data from a custom
memory-backed data store via a java api. When looking at performance,
there is a hotspot at the point of interaction with this API. One of the
fields of each record being exported contains a list of lists of strings
(List>)
