Red Hat Enterprise Linux 6: Performance advantages with an

open source software stack

Configuring the DVD Store client servers

Each DVD Store client simulates 30 simultaneous users of one DVD Store Web site. In order to generate an

appropriate workload, we assigned two clients to each DVD Store Web site, or 60 simultaneous users. Accordingly, six

client servers, each running 32-bit Microsoft Windows Server 2003 Enterprise with Service Pack 2 were prepared with all

Windows updates as of 1/16/2012 applied.

We copied the DVD Store web-client for MySQL, ds2webdriver.exe, to the directory c:\ds2\bin on each client.

We created a DVD Store parameter file, params.txt, on each client with the following contents (the target IP address

changed to that client’s target Web site).

target=192.168.30.21

n_threads=30

ramp_rate=1

run_time=30

db_size=10GB

warmup_time=10

think_time=0

n_searches=3

search_batch_size=5

n_line_items=5

Testing procedure

To perform the test, we used a batch file, which we executed from the client machine. We stored the batch file

in the C:\ClientShare folder. The testing procedure consisted of the following steps:

1. Execute the batch file.

2. Stop the MySQL services.

3. Delete all prior database files.

4. Copy all original database files from the backup utility partition.

5. Reboot the server under test.

6. Reboot the client machine.

7. Wait for a ping response from the physical server machine.

8. Wait 10 additional minutes for any background tasks to complete.

9. Mount all necessary partitions.

10. Start the MySQL services.

11. Start the workload ramp up period.

12. Stop the workload.

13. Start the workload.

14. Stop the workload.

15. Copy all output files.
