#16034: Quadratic GC slowdown using RTS debug -------------------------------------+------------------------------------- Reporter: remyo | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Runtime System | Version: 8.6.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by remyo): The original intent was not to explicitly use debugging runtime but ticky profiling (which implies debugging runtime). It is of course natural to expect some slowdown (2x, 3x, 10x or even more). But in the real world example I was testing, the program was still not finished after more than 10 hours, where the regular compiled binary finished in 4 minutes. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16034#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
