Read [http://www.haskell.org/haskellwiki/Numeric_Haskell:_A_Repa_Tutorial#Optimising_Repa_programs the optimisation section] in the tutorial, then [http://stackoverflow.com/questions/6300428/poor-performance-with-transpose-and-cumulative-sum-in-repa This Answer] on Stack Overflow. If that doesn't help then continue to the next question.34 A: Probably because you haven't forced your source arrays before traversing them, or haven't added enough INLINE pragmas.
