Thanks a lot.
Yes, both statements are generally true. That said, since Go's garbage collector runs concurrently with the rest of the program, it's a little hard to know what "the time cost of the mark phase" is. But it is true that in general during marking the GC only looks at live objects. Ian -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
