Object
Lazy Write Flushes/sec is the frequency the Cache's Lazy Write thread has written to disk. Lazy Writing is the process of updating the disk after the page has been changed in memory, so the application making the change to the file does not have to wait for the disk write to complete before proceeding. More than one page can be transferred on each write operation.
