#12706: Collecting type info is slow -------------------------------------+------------------------------------- Reporter: vshabanov | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: GHCi | Version: 8.0.1 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- With `:set +c` option in GHCi, I'm waiting for 10-15 seconds for {{{ Collecting type info for 34 module(s) ... }}} after both first load and subsequent reloads, even if only top-level module was modified. And GHCi uses about 1.5-2x more memory than it uses without `:set +c`. My app has about 30k lines of code. Is it expected behavior and some performance improvements are planned or it's a bug? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12706 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
