Server Performance

By jmiller ·
I have gigabit capable switch, and all 10/100 NICs in servers and PCs. I'm considering adding gigabit NICs to all of the servers. What type of performance boost should I expect, and does this strategy even pass the cost/benefit analysis test?

Thanks,

Jimmy

Fast Ethernet use four wires for commnuicate and giga Ethernet use all wires for communication.

Mostly therotically able to run gigabits. In reality I think it is able to transfer at 300-400Mbps (It will vary depend on the numbers of client computers)

do u agree?

The performance gain that you will see will greatly depend on the traffic that is going across the wires on your network. If you are doing simple file and print sharing, you will probably not notice much of a change. However, if you are running a SQL server or a streaming media server for your internal network, then the performance gain would be greater. Basically, the faster NIC allows for more bandwidth to pass between the server and redirector. If you are using apps that hog bandwidth, then you should see a significant performance gain with a faster NIC.

Whether you'll see a performance boost, and how much of one, depends on where your bottlenecks are. If the bottleneck is currently your server CPU, you would see little or no improvement. On the other hand, if the network link is a bottleneck, theimprovement can be significant.

To tell where your bottleneck is, you can set up some Performance Monitor sessions and watch them for awhile. In particular, you'll want to look at the Network Interface Object and the Server Work Queues. Over time, you'll be able to develop a sense of whether upgrading to Gigabit will actually move the packets any faster.

Generally by using gigabit ethernet, the network performance will improve. How much it'll improve the network is varies. You may expect 3 to 5 times improvement depend on your application used and server performance.
In the side of cost/analysis, you can gain benefit if you're running time sensitive application.

goodluck

as those before me answered the improvment realy depends on where your bottleneck is. in most cases if you are working already on "100 mb full duplex" a load balancer will help much more than a faster nic per server. most disk cpu combanations wont work faster than 450 mb.
