I am pleased to announce a new release of network-bytestring, a Haskell library for fast socket I/O using ByteStrings. New in this release is support for scatter/gather I/O (also known as vectored I/O). Scatter/gather I/O provides more efficient I/O by using one system call to send several separate pieces of data and by avoiding unnecessary copying. I would like to thank Brian Lewis, Bryan O'Sullivan, and Thomas Schilling for contributing patches for this release. Get it: cabal install network-bytestring And on Hackage: http://hackage.haskell.org/cgi-bin/hackage-scripts/package/network-bytestrin... Windows hackers needed: I've made sure that the library builds on Windows but since I don't use Windows myself I haven't implemented scatter/gather I/O support for Windows. It should be straightforward to add and I'd be happy to review the patches. Cheers, Johan
