- As part of
MDEV-21212we switched to use distributed counter (default to atomic) for tracking page access (n_page_get).
- Originally the counter was non-atomic and so represented an approximate value of the page access. Using the same analogy we could continue to use a non-atomic distributed counter that helps get an approximate count.
- this change helps improve performance slightly in the range of 3-8% especially in more contention cases.
