Re: [Haskell-cafe] using Map rather than FiniteMap

I didn't find any such information. I just decided to look at the FiniteMap source code in CVS and discovered in the comments that it was deprecated in favor of Data.Map. So I downloaded the new Data.Map and Data.Set and ran the code I posted before. I executed basically instantly and used minimal memory. I think Map picked up a lot of speed because it doesn't spaceleak, but am not sure. -Alex- On Tue, 25 Jan 2005, Ketil Malde wrote:

Just did a search after my last post and learned that FiniteMap is bad. Discoverd that Data.Map is the intended replacement. Downloaded it and modified it to work with 6.2. Blazingly fast!

Oh? I was aware that Data.Map was supposed to be better, but not that FiniteMap was particularly bad. Is there any information about when, why and by how much Data.Map is better?
