#8732: Global big object heap allocator lock causes contention -------------------------------------+------------------------------------- Reporter: tibbe | Owner: simonmar Type: bug | Status: new Priority: normal | Milestone: 7.12.1 Component: Runtime System | Version: 7.6.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by tibbe): What about the idea of just using malloc? Modern mallocs like TCMalloc are already multithreaded and seem to just deal with all the annoying issues. Gregory Collins said that in Snap they just don't use the "built-in" ByteString construction functions and instead just call malloc. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8732#comment:15 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
