Esto le indicará el número de veces que se ha ejecutado una consulta y la consulta más larga para ejecutar.
No estoy seguro de si esto va a ser útil o no, pero este SQL le dará la más lenta 100 consultas:
SELECT TOP 100
[Object_Name] = object_name(st.objectid),
creation_time,
last_execution_time,
total_cpu_time = total_worker_time/1000,
avg_cpu_time = (total_worker_time/execution_count)/1000,
min_cpu_time = min_worker_time/1000,
max_cpu_time = max_worker_time/1000,
last_cpu_time = last_worker_time/1000,
total_time_elapsed = total_elapsed_time/1000 ,
avg_time_elapsed = (total_elapsed_time/execution_count)/1000,
min_time_elapsed = min_elapsed_time/1000,
max_time_elapsed = max_elapsed_time/1000,
avg_physical_reads = total_physical_reads/execution_count,
avg_logical_reads = total_logical_reads/execution_count,
execution_count,
SUBSTRING(st.text, (qs.statement_start_offset/2) + 1,
(
(
CASE statement_end_offset
WHEN -1 THEN DATALENGTH(st.text)
ELSE qs.statement_end_offset
END
- qs.statement_start_offset
) /2
) + 1
) as statement_text
FROM sys.dm_exec_query_stats qs
CROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) st
ORDER BY total_worker_time/execution_count DESC
Estos son protectores de la vida. Podría ver al instante qué consultas no se han podido almacenar en caché. – JakobMillah
