#13165: Speed up the RTS hash table -------------------------------------+------------------------------------- Reporter: dobenour | Owner: Type: bug | Status: new Priority: normal | Milestone: 8.2.1 Component: Runtime System | Version: 8.1 Resolution: | Keywords: 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 simonmar): This would be great - are you planning to do it? To avoid the indirect calls don't we need to specialise the hash table to the key type? There are at least two key types in use (strings and pointers). Also, couldn't we pull in a good third-party hash table implementation instead of writing our own? When I was working on the compact code I did try https://troydhanson.github.io/uthash/userguide.html but it was slower than the RTS hash table. I'm sure there are better ones. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13165#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
