Can this be done by doing this,

 unsigned n = mymap.bucket_count();
  float m = mymap.max_load_factor();
  if (m > 1.0) {
    return (n * m) * (sizeof(value_type stored));
  }
  else {
    return n  * (sizeof(value_type stored));

to get an approimate size?

I got this idea from this question's answer - https://stackoverflow.com/questions/25375202/how-to-measure-memory-usage-of-stdunordered-map

Thanks!

Hi,

I need help in determining the amount of memory used by boost::unordered_multimap and boost::unordered_multimap. We have a large code base and we have some optimizations done using boost::unordered_multimap and boost::unordered_multimap. The speed it really good, but we want to measure the amount of space it is occupying.

Can somebody please help with that?

I would not be able to change to use a custom new/delete.

Thanks
