#7602: Threaded RTS performing badly on recent OS X (10.8?) ---------------------------------+------------------------------------------ Reporter: simonmar | Owner: Type: bug | Status: new Priority: normal | Milestone: _|_ Component: Runtime System | Version: 7.6.1 Keywords: | Os: Unknown/Multiple Architecture: Unknown/Multiple | Failure: None/Unknown Difficulty: Unknown | Testcase: Blockedby: | Blocking: Related: | ---------------------------------+------------------------------------------ Comment(by simonmar): Does the support for TLS compile down to calls to `pthread_getspecific`/`pthread_getspecific`? If so, that won't help much - we could remove some hacks from the code, but it will still perform badly. Someone with a Mac will need to do some measurements to be sure. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7602#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
