Your claim is " It is a fast as the popular smart pointer * boost::shared_ptr<T>*". Yet, in single-threaded code and shared_ptr using new instead of make_shared, block_ptr still takes 3.3x as long as shared_ptr.
That is *a lot* of overhead...
Yes but this is a worse-case scenario because the assignment of a pointer from the data segment that is the last one pointing to an object on the heap will go thru more subroutines. If the pointer was already on the heap then it'll be faster. What really matters is the constant complexity. But you're right on the docs I'll correct them. My point is to optimize ordered_malloc() and is_from() and I was wondering if there is any hope that can happen? Thanks, -Phil
