Brother-Eagle™ Oracle Performance
Advice: # Blocks Written/Sec

This parameter is impossible to benchmark from one database to another.  This parameter should be used to identify spikes in activity based on what is normal in your database.  For instance, if 3.5 blocks/sec is normal write activity for your database, then you can set your thresholds accordingly to signal alarms above or below this number.  If throughput is down, either the database does not have an opportunity to perform that many writes or it could be a performance issue.
