#13395: 3x slowdown on GHC HEAD with file containing lots of overloaded string literals -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: (none) Type: bug | Status: new Priority: high | Milestone: 8.2.1 Component: Compiler | Version: 8.1 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 rwbarton): I took a look but on my systems it doesn't compile in anywhere near 3.5 seconds under GHC 8.0.2. It takes about 15 seconds for me and a recent (but not absolutely up-to-date) HEAD is similar. RyanGlScott are you sure about these numbers? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13395#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
