Can you share a comparison on what sort of benefit you see with and without this?

For a heap dump with 330M objects, this change reduced the storage from ~9GiB (which is greater than the 8GiB gcdump limit of my modified build) to 6.22GiB. This is a prerequisite to upcoming work that doubles the amount of data PerfView can load at once.
