WebGHC >=8.10 is getting a new incremental garbage collector with a mark&sweep strategy for the older generation collections, as an alternative to the standard copy collector. Incrementality comes from performing the sweep phase concurrently with the mutator (i.e. the program), after a blocking, hopefully short marking phase. skinny food promo code

"WebHaskell/GHC garbage collection How different is the garbage collector of a language like Haskell compared to the one of a language like Java. Objects in Haskell are typically immutable and IDless. Programmers have a much more restricted control over objects, which, I guess, is translated to easier job for the GC.

An unused … WebThe command line option -verbose:gc causes information about the heap and garbage collection to be printed at each collection.
