Abstract
A method and system for collecting statistics associated with multiple memory nodes to determine if a read-only page is read accessed in aggregate by multiple processing devices of the multiple memory nodes at or above a first threshold value. If so, the read-only page may be replicated to an additional memory node. If a determination is made that the read-only page is read accessed in aggregate by the multiple processing devices below the first threshold value, the read-only page may be de-replicated upon receipt of a write request associated with the read-only page.
