#16040: Unboxing-Related Performance Issue with Polymorphic Functions -------------------------------------+------------------------------------- Reporter: _recursion | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.6.2 Resolution: | 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: | -------------------------------------+------------------------------------- Comment (by simonpj): I have not yet tried with criterion, but I tried with {{{ main = print (test1 10000000) }}} or `test2`, and ran with `+RTS -s`. I got the same amount of allocation either way. Do you see that too? If so, it's not a heap-allocation issue. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16040#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
