”Inserts” provides detailed information about the types of inserts taking place on heap tables (including partitioned heap tables), clustered tables, and all inserts as a percentage of all insert, update, and delete operations. It displays the number of inserts performed on:
Allpages-locked heap tables
Allpages-locked tables with clustered indexes
Data-only locked tables
Insert statistics do not include fast bulk copy inserts, because those are written directly to the data pages and to disk without the normal insert and logging mechanisms.
