Query with 0.01% of Query cost occupies 80% on time of a stored procedure... - Microsoft SQL / MS SQL Server

    Hi Faustino,

    The costs reported in the Execution plans are unreliable in certain
    situations, for example when temporary tables are involved. Run a trace in
    SQL Profiler to get reliable information about the duration, cpu usage and
    number of page reads.

    Ok, great! Now the things begin to look on their foots...
     
    Anyway, the cost reported in the Execution plans is related to CPU usage or
    execution time?

    Thanks you
    Faustino

    The costs reported in the execution plan take all resource usage in account:
    cpu, disk reads, udration, memory etc. It is not related to just one
    parameter.

    One thing that is always the same for an execution plan (using the same data
    of course) is the number of logical reads, which you can get with SET
    STATISTICS IO on.
