Thanks Grant for these leads.

I am not experienced with extended events, so I started digging with sys.dm_exec_query_stats. Particularly with total_physical_reads. But what I can use to join two snapshots of this view (I will run this view twice and then calculate the delta between total_physical_reads) ? The only good candidate looks sql_handle.

About XE, can you point me to a query/script that I can use ?

Thanks
