#15366: GHC.Conc.Windows has a surprising queue -------------------------------------+------------------------------------- Reporter: dfeuer | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.8.1 Component: Core | Version: 8.4.3 Libraries | Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: Runtime Unknown/Multiple | performance bug Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- `GHC.Conc.Windows` seems to use `[DelayReq]` as a priority queue, and uses `foldr` to insert multiple elements into it. Unless these lists are always very short (are they?) that seems like a bad idea. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15366 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
