#10693: Profile ghc -j with an eye for performance issues -------------------------------------+------------------------------------- Reporter: bgamari | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.1 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: Compile-time Unknown/Multiple | performance bug Test Case: | Blocked By: Blocking: | Related Tickets: Differential Revisions: | -------------------------------------+------------------------------------- `ghc -j` doesn't seem to scale as well as it could. Reports claim that even packages with embarasssingly parallel module structures (e.g. `highlighting-kate`) only scale out to three or so processors. Profiling a parallel build would be a useful first step to finding out why. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10693 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
