#8224: Excessive system time -- new IO manager problem? -------------------------------------+------------------------------------- Reporter: rrnewton | Owner: Type: bug | Status: new Priority: high | Milestone: 7.8.1 Component: Runtime System | Version: 7.7 Resolution: | Keywords: IO Manager, Operating System: Linux | System Time Type of failure: Runtime | Architecture: x86_64 (amd64) performance bug | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------- Comment (by AndreasVoellmy): Actually, I can simplify the program to just {{{ main = return () }}} and I get 200ms in kernel when run with -N32. I'm not sure how significant this 200ms time is - I guess it is time spent initializing or cleaning up capabilities (possibly including IO manager resources). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8224#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
