Page Life Expectancy is the number of seconds the average page of data has been in the buffer pool.SQL server keeps data pages in memory for quicker access instead of having to read from disk every time. Now, keep in mind that Page Life Expectancy doesn’t prove or disprove anything on its own. It’s simply a symptom of potential memory pressure. If you think that your server is suffering from some sort of memory pressure, this is just one piece of a bigger puzzle that can help
