Neither benchmarked nor used it, but just to make sure: did you notice that the comment says 128KB strings for ps and lps, but they are in fact 1MB strings: -- 128KB strings ps = B.replicate (2^20) 0 lps = L.replicate (2^20) 0 ? If not, the throughput would look much better, wouldn't it? _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
