sys.dm_db_index_operational_stats

  • Hello.
    I have 4 instalations:
    10.50.6220.0 (2008R2)
    11.0.5556.0 (2012)
    12.0.4100.0 (2012)
    12.0.5000.0 (2014)
    The four are differents in number of cores, ram, SAN and workload.
    This DMV works fine (0.01 - 0.1 seconds per table),  but in 12.0.500.0 works very poor (average 0.5 seconds)
    His workload is less than the other three instalations.
    some idea for this?
    Thanks.

  • What parameters if any are you using and what is the size of the data returned ?

  • Hello RandomEvent.
    The 4 instalations have the same application.
    The parameters are id from database, id from table, id from any index and default for partition.
    Few rows for execution (usual, one row, it is a OLTP, all tables with PK but only a few tables with more index).
    More or less, DMV returns 346 bytes per row.
    Thanks.

  • The I/O subsystems are not the same which can make a big difference.
