#14964: performance regressions from 8.0.2 to 8.4.1 -------------------------------------+------------------------------------- Reporter: elaforge | Owner: (none) Type: task | Status: infoneeded Priority: normal | Milestone: Component: Compiler | Version: 8.4.1 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: | -------------------------------------+------------------------------------- Changes (by simonpj): * priority: high => normal Comment: The productivity number is down sharply, and consistently so, which translates directly into longer run times. Somehow, although residency (well max-memory-in-use at least) is not increasing, GC time is greatly increased. It'd be really good to characterise this some more. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14964#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
