That is, a sequence of [AAABBB] may be traversed faster than [ABABAB] for such a container, and I believe in the later case such that the types are uniformly distributed, vector<variant> will perform better. I wrote something on this some time ago, maybe worth having a look at:

Interesting read, thanks for the links. Although in this case we are talking about vector<variant> which stores data by value.
