#14594: 2 modules / 2500LOC takes nearly 3 minutes to build -------------------------------------+------------------------------------- Reporter: schyler | Owner: dfeuer Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by dfeuer): Some good news: this appears to build much more quickly (1m13s real time) using the `nightly-2017-12-18` resolver (ghc-8.2.2) as with the 8.0-based `lts-9.18` resolver (which took 2m9s). Of course, those resolvers also differ in other ways. I'm still reducing the test file, and I'll report back when I have a better sense of the real difference. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14594#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
