#14414: Profiled program runs 2.5x faster than non-profiled -------------------------------------+------------------------------------- Reporter: Fuuzetsu | Owner: (none) Type: bug | Status: infoneeded Priority: normal | Milestone: Component: Compiler | Version: 8.2.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by Fuuzetsu): I believe I was on NixOS, IIRC Intel i7 6700k CPU on 8.2. That machine is on another continent and I won't be able to retry the experiment... If someone can confirm the bug doesn't occur on Linux with modern GHC, I'm happy for the ticket to be closed. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14414#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
