#8158: Replace IO manager's IntMap with a mutable hash table -------------------------------+------------------------------------------- Reporter: bos | Owner: AndreasVoellmy Type: feature | Status: patch request | Milestone: 7.8.1 Priority: high | Version: 7.7 Component: | Keywords: libraries/base | Architecture: Unknown/Multiple Resolution: | Difficulty: Easy (less than 1 hour) Operating System: | Blocked By: Unknown/Multiple | Related Tickets: Type of failure: Other | Test Case: | Blocking: | -------------------------------+------------------------------------------- Comment (by bos): That matches what I see: a nice performance bump with a small number of cores, and it's harder to see an effect as the number of cores increases. (No idea why, but presumably it means there's a bottleneck somewhere else as the core count rises.) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8158#comment:20 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
