update-in* performance
update-in* version 5 offers notable performance improvements for nested hashmaps and nested vectors.
See the overall summary for benchmarking details. The benchmarks displayed in this document are defined here.
Hashmaps
Version 5 improves performance to within 18% of clojure.core/update-in when handling hashmaps.
