For small amounts of data, the overhead erases the performance gains - although no one is denying that for medium (like you see on the Shootout) to large amounts of data (up to tera-, I think someone benchmarked) ByteString is excellent. -- gwern O/S bet pipe-bomb SARA Adriatic BSS M5 LBSD NOCS CBNRC
