#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 simonmar): 200ms spent doing unspecified "initialization" should definitely be investigated, that's a lot. I can't see anything useful in that call stack, it looks like it might be related to signals or epoll() but it's hard to tell anything else. What does the `+RTS -s` look like? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8224#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
