Difference in Execution speed depends on USER ????

  • IO wonder if anybody has any experience with this.

    We have a scheduled job that takes about 1.5 hours to complete. The Job is a C++ program that does a lot of inserts from another database. (on the same server)

    If the SQLServerAgent runs under LocalSystem the tool is finished in 1.5 hour. If we run the SQLServerAgent under anotheracount ( Local Administrator) it takes about 2.5 hours........

    Unfortunately the job also needs to copy data from a network share so the jo has to run under a Domain User Account.

    Does anybody has any Idea why it could make such a difference ???

    I looked into profiles etc and there is nothing that could explain the difference....

    or is there ?

  • I thinks that it has to be with permissions in the operating system

  • You can see a simialar result with the backup command. The time it takes in a maintenance plan is much less than the time it takes in QA. Probably something to do with job priority, Internal sql commands get priority over external sql commands
