Read-write page evicts Indicates the number of read-write pages discarded from the cache to make
room for new pages. This value differs from Pages Written Out in that these
are discarded read-write pages that have not been modified.
Pages discarded from the cache have to be written to disk, possibly affecting
server performance. The lower the number of page evicts the better.
