#9706: New block-structured heap organization for 64-bit -------------------------------------+------------------------------------- Reporter: ezyang | Owner: gcampax Type: task | Status: new Priority: normal | Milestone: Component: Runtime | Version: 7.8.3 System | Keywords: Resolution: | Architecture: Unknown/Multiple Operating System: | Difficulty: Unknown Unknown/Multiple | Blocked By: Type of failure: | Related Tickets: None/Unknown | Test Case: | Blocking: | Differential Revisions: D524 | -------------------------------------+------------------------------------- Comment (by simonmar): Anything less than 2% is probably noise, unless you can reproduce it consistently and/or there is some objective measurement such as number of instructions or memory reads using perf. There are other random effects that can cause small wobbles, even code placement by the linker or alignment effects. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9706#comment:19 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
