Performance week 25/6-29/6

[Bauer, Christoph]

Hi,

I must start by saying, that I don't have any knowledge about 
ghc internals. 

Performance of haskell programs seems to me heavily 
depended on the data structures of a simple linked lists.
Because of the amount of cons-cells, simple linked lists
aren't very GC-friendly. 

There is a paper about a replacement, called VLists.

So maybe VLists could be used in haskell internally for lists and
strings.

Best regards,
