Maximizing Queuing System Performance  

• CPUs--CPU speed and availability are important on the nodes on which the queue managers are running. The more time the queue manager has and the faster the CPU, the faster the queue manager can process information.



• Disks--Disk speed as well as nonqueuing activity (such as paging and heavy access to the database) on the database disk can affect performance.

Use the following methods to maximize your queuing system's performance:

• Maintain queue manager processes on the fastest and most available nodes in a cluster. (See Understanding the Queue Manager.)



• Create an additional queue manager to run on another node to distribute the CPU load on heavily used queuing systems. (See Using Multiple Queue Managers.)



• Move queue and journal files to disks with less activity or higher speeds. (See Starting the Queue Manager and Creating a Queue Database.)
  
  Note that moving the master file provides little difference in performance.
