Database access speeds up when priority lowered?

Question

I found very consistent performance problems executing a
straightforward SQL query against a large database which mysteriously
went away when we lowered the priority of the thread to 5.
Running on a database that has about 100000 records, with 47 fields
(TEST.MDB is 41MB), the code below ran in 300 milliseconds if the
priority is 5 or less and over 30 seconds if the priority is 6 is more.
Any ideas why this is happening?

Connection con=DriverManager.getConnection(
        "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=TEST.MDB");
Statement stmt=con.createStatement();
ResultSet rs = stmt.executeQuery(
        "SELECT A, sum(1) AS SUMOFCOUNT FROM T WHERE B = 'I' GROUP BY A");
Thread.currentThread().setPriority(6);
ResultSet rs = stmt.executeQuery(
        "SELECT A, sum(1) AS SUMOFCOUNT FROM T WHERE B = 'I' GROUP BY A");

Hi Mike,
No simply way. Most of the Viewers are for viewing reports with saved data. For them to run your reports on their work stations they too need to install CR Designer.
If you have access to a developer you could write a very simple application so they could refresh the reports. Then all they have to do is deploy the runtime on their PC's, that is free for distribution to internal use only.
There may even be some sample applications you could use but you'll need help from a developer to make it work properly.
Thank you
