#8835: 7.6.3 vs 7.8-RC performance regression --------------------------------------------+------------------------------ Reporter: cbm80 | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.1-rc2 Resolution: | Keywords: Operating System: Linux | Architecture: x86_64 Type of failure: Runtime performance bug | (amd64) Test Case: | Difficulty: Unknown Blocking: | Blocked By: | Related Tickets: --------------------------------------------+------------------------------ Comment (by carter): could you compile the program with 7.8 using -fno-full-laziness and give us the perf info then? (theres 1-2 example programs we've seen where adding -fno-full-laziness will resolve the change in performance characteristics) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8835#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
