I've updated the clojure.zip implementation to use records internally. This achieves a speedup of roughly 2x. You can find the library below and on clojars:
https://github.com/akhudek/fast-zip It's a drop in replacement for clojure.zip in terms of interface and usage. However, since the internal representation has changed, fast-zip locations cannot be used with the clojure.zip implementation. E.g. you cannot create a zipper with fast-zip, then use clojure.zip/next on the result. You must use fast.zip.core/next instead. In addition to the micro-benchmark provided, I've tried this in a larger project that makes extensive use of zippers and found a similar speedup. Comments and suggestions welcome.
