dissoc* performance
Compared to version 4, dissoc* version 5 notably improved performance handling hashmaps. Handling other collection types
remained constant.
See the overall summary for benchmarking details. The benchmarks displayed in this document are defined here.
Hashmaps
Version 5 improves performance on hashmaps by 40 to 60% compared to version 4.
