There has been a lot of talk about Haskell performance recently, particularly in relation to the shootout benchmarks, with many useful techniques being mentioned. Some of this information is already available in various bits of documentation, and some of it is only emitted in small nuggets by people like me when they are prodded in the right places (sorry :-). So I felt motivated to start organising some pages on the wiki where we can collect performance-related wisdom. Here it is: http://haskell.org/haskellwiki/Haskell_Performance_Resource The content is quite thin right now, but I hope others will start adding stuff (and by all means fiddle with the structure too - nothing's set in stone). I've added some material from GHC's user guide, and I plan to move the rest of the performance-related material from there in due course. Cheers, Simon
