So, the cache that has been referred so far is the operating system virtual memory manager caching and not something specific to bzr. If this is the case, then the same caching concepts will work for any application using VM. Is bzr coded differently to make use of such a feature in a different way? I am interested in exploring this to find out if it can help performance or just a myth. -dhruva
