haskell-blaze-builder (Efficient buffered output)

This library provides an abstraction of buffered output of byte

streams and several convenience functions to exploit it. For

example, it allows to efficiently serialize Haskell values to lazy

bytestrings with a large average chunk size. The large average

chunk size allows to make good use of cache prefetching in later

processing steps (e.g. compression) and reduces the sytem call

overhead when writing the resulting lazy bytestring to a file or

sending it over the network.
