#13220: Performance regressions in testsuite from join points -------------------------------------+------------------------------------- Reporter: lukemaurer | Owner: lukemaurer Type: bug | Status: new Priority: highest | Milestone: 8.2.1 Component: Compiler | Version: 8.1 Resolution: | Keywords: JoinPoints 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 rwbarton): Another data point: The total time it to finish the stage1 build (which does include some time spent not in ghc, like running configure scripts) increased from 1208s to 1272s when moving from `ghc-HEAD-before-join` to `ghc-HEAD-after-join` as the bootstrapping compiler, an increase of 5.3%. That's roughly consistent with the 6% increase in `DynFlags.hs` build time mentioned in the previous comment. Still not wonderful, but also not nearly as bad as the total build time regression would seem to indicate. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13220#comment:15 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
