#9233: Compiler performance regression ---------------------------------+------------------------------------ Reporter: augustss | Owner: Type: bug | Status: new Priority: low | Milestone: Component: Compiler | Version: 7.8.2 Resolution: | Keywords: Operating System: Windows | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: ---------------------------------+------------------------------------ Old description:
Compiling all of our Haskell modules (about 1300 modules, 310 kLOC) takes about 30% longer with ghc 7.8 than it did with ghc 7.2. (Using 32-bit Windows.)
Sorry, I can't really provide any simple test case.

Sorry, I can't really provide any simple test case. -- Comment (by augustss): Oops, I meant to say ghc 7.6, not 7.2 in my bug report. If I have some time I'll try to find a single module where the compilation has slowed down, and see if I can profile that. Is there a way to get hold of a profiling ghc binary? Compiling ghc on Windows always takes a few days to get working. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9233#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
