Maximizing MSMQ Messaging Performance

MSMQ independent clients and servers can use up to three different drives to store the message files, message-logger files, and transaction-logger files. The drives must be local physical drives. If you have only two drives, store the message files on one drive and the message-logger and transaction-logger files on another drive.

Note In the Windows NT operating system, two or more IDE drives accessed through the same controller cannot be accessed simultaneously. Therefore, to benefit from having the data and log devices on separate physical drives, either use SCSI drives or use two IDE controllers.

• In Control Panel, double-click MS Message Queue.
• On the Storage tab, specify different physical drives.
If you do not specify an existing folder, MSMQ creates the folder, as long as the parent folder already exists. For example, MSMQ creates the D:\Sorage\Msmq\Msgfiles folder only if the D:\Sorage\Msmq folder already exists.
• When prompted to stop services, click Yes.
• When prompted to shut down and restart Windows, click Yes.

For information on using Performance Monitor to determine if additional hard disk drives will improve messaging performance, see "Monitoring MSMQ Messaging Performance" in Chapter 4, "Monitoring Your MSMQ Enterprise."
