#9989: GHCI is slow for precompiled code -------------------------------------+------------------------------------- Reporter: remdezx | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: GHC API | Version: 7.8.3 Resolution: | Keywords: Operating System: Linux | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by remdezx): Yes, it is still slower when it is run on CPU. When I change `import Data.Array.Accelerate.Interpreter as C` to `import Data.Array.Accelerate.CUDA as C` compiled code for matrix size `10000` executes `0.007s` and precompiled and run under ghci is `0.035s` (5x slower). For `1000000` matrix size execution times are `0.57s` (compiled) vs `0.90s` (precompiled). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9989#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
