    Checkpoints are internal operations. They won't show up in profiler

    You can log the output of:

    SELECT * from sys.dm_exec_requests where session_id < 50

  • RE: Same Store Proc run 100x slower in identical sql-server setup

    I assume that you mean that each are setup in a Dev db on the same server.
