Data Warehouse Test

We are always looking to improve the quality of our reviews and as a result, we have added a new Stress Test to our suite.

This "Data Warehouse" test is focused on large record sets with plenty of aggregation. This test is based on a system that we developed to track and manage Request statistics for www.AnandTech.com and Forums.AnandTech.com. It tracks statistics like Requests/Hour, Requests/Hour/IP Address, Unique IP Addresses/Hour, Unique Users/Hour, Daily Browser stats, etc. These stats are further summarized by site, i.e. www or Forums.

As with the other Stress Tests, each test was repeated three times and the average between the three tests was used. For this Data Warehouse Stress Test, we defined a quantity of work to complete and measured how long each platform required to process the workload.

So, to ensure that IO was not the bottleneck, each test was started with a database, including tempdb, which had already been expanded so that autogrow activity did not occur during the test. During the execution of the tests, there were no applications running on the server or monitoring software. Task Manager, Profiler, and Performance Monitor were used when establishing the baseline for the test, but never during execution of the tests.

At the beginning of each platform, the server was rebooted to ensure a clean and consistent environment. The database was always copied to the 8 disk RAID 0 array with no other files present to ensure that file placement and fragmentation were consistent between runs. In between each of the three tests, the database was deleted, the original database was copied again to the array, and SQL Server was restarted.

There is no "client" required for this test. The workload is initiated by a stored procedure call from Query Analyzer.
