>From my experience I can recommend msgpack (<a href="http://hackage.haskell.org/package/msgpack">http://hackage.haskell.org/package/msgpack</a>) as being extremely fast. It comes with optimized prepared instances for common data structures which is very nice, because you don&#39;t have to roll your own version with library like cereal (which is indeed very fast, but simply less convenient).<div>
