thread-local-storage: Several options for thread-local-storage (TLS) in Haskell.
Thread-local storage, or TLS, is an important ingredient in many algorithms and data structures.
The GHC compiler does not provide a built-in notion of TLS either at the IO-thread or OS thread level. This package provides a few different implementations of a simple TLS API.
All exported public modules provide exactly the same interface with different implementations. Run the included criterion benchmark suite to ascertain which performs the best on your platform.
Example criterion benchmark data can be found here (from an Intel Ivy-Bridge i7-3770 desktop): http://www.cs.indiana.edu/~rrnewton/datasets/xmen_tls_report.html

Here are some example benchmark results (on an Ivy Bridge i7-3770), with a typical time of 10.4 nanoseconds to get to a TLS variable given one IO thread per OS thread:
