High read rate (virtual):<number of> pages per command, <number of> virtual reads, <number of> commands
Explanation
The application contains statements that require a large number of logical database cache reads. The only way to determine if this is a problem is to examine the application profile. For example, an application containing a large number of mass selects with relatively unspecific WHERE clauses will lead to a high number of virtual reads.
User action
Check to determine whether the SQL statements executed in the application are actually reading much more data than is actually required for processing.
