#9646: Strange performance bug -------------------------------------+------------------------------------- Reporter: erikd | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.3 Resolution: | Keywords: Operating System: | Architecture: Unknown/Multiple Unknown/Multiple | Difficulty: Unknown Type of failure: Runtime | Blocked By: performance bug | Related Tickets: Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by dfeuer): I don't know what's going on, but I'm curious whether there might be some sort of interference from `make` or associated OS or CPU stuff. Have you tried running the benchmarks separately from the compilation process? Another thing to experiment with is reversing the order of the Criterion benchmarks to see if the slowness follows the position in the benchmark list. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9646#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
