STMContainers

Depends on 7 packages(full list with versions):

base, base-prelude, focus, hashable, list-t, primitive, transformers

Used by 4 packages in lts-7.24(full list with versions):

slave-thread, Spock, stack-run-auto, timemap

This library is based on an STM-specialized implementation of a Hash Array Mapped Trie. It provides efficient implementations of Map, Set and other data structures, which are slightly slower than their counterparts from "unordered-containers", but scale very well on concurrent access patterns.

For details on performance of the library see this blog post.
