#15891: Excessive system time during execution of GHC-built executables on macOS ---------------------------------+---------------------------------------- Reporter: goldfire | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.3 Component: Compiler | Version: 8.6.2 Resolution: | Keywords: Operating System: MacOS X | Architecture: Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | ---------------------------------+---------------------------------------- Comment (by goldfire): I should add a few details, inspired by comment:4 - My BuildFlavour = devel2 - Used `make -j5` I needed to `chmod u+s` `dtruss` to get it to work... but then, later, had trouble and so had to revert this change. Just posting here to avoid @gridaphobe problems later. To sample, I ran `sample ghc-stage1` while GHC was compiling in another terminal session. Glad to know I'm not alone here! -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15891#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
