Could someone help me to make this code faster? I'd like to see solution that will be elegant and fast, without heavy optimizations, that will make code unreadable. Also, if it possible, prepare the program to support SMP parallelism.
The solution's already been posted, but to make this particular code faster, I recommend using Data.Trie instead of Data.Map ByteString. Tries are faster for lookup since they don't redundantly check the prefix of the query; also they're better for memory usage because they don't store redundant copies of the prefixes. http://hackage.haskell.org/cgi-bin/hackage-scripts/package/bytestring-trie -- Live well, ~wren
