High-speed network adapters and network drivers optimize MSMQ server performance. High-speed network adapters can achieve high throughput rates with low CPU use.
Because many dependent clients and independent clients will simultaneously access the server, you should install one or more high-performance network adapters, based on a high-speed bus such as PCI or EISA. Installing multiple adapters in a multiprocessor server means that a single server can handle more requests, with each adapter servicing a separate network segment or protocol.
You can use two network adapters to provide fault tolerance. To do so, associate the CNs supported by the computer with both network adapters.
