NIC Usage

[techyphil]

Just been looking at the network load on the servers and considering we've got about 600pc's and atleast 150 on at anytime, the network usage graph in WinServer 2003 averages out about 2-5 %. Is that normal?? We have slow logon times yet it hardly changes. Whereas our admin server peeks at times to 70%.

I'll look at it more closely but ive checked over the network links and all appears fine.

What's your network usage on a server?

Thanks

Its a 1GB NIC btw and the Network Utilization is at about 0.1% - 1%. Peeks to 5% at times..

Ive found the same thing on our servers, even on DC's it never goes above 5%

We dont really have any speed issues though so its not something Ive investigated any further

Ok great, thanks sidewinder

I suppose it could just mean in my case there are no bottlenecks and in your case the bottleneck is somewhere other than the NIC? Disks or memory perhaps?

I pulled the interface stats out of cacti for a few of our servers.

There are many reasons why your server isn't max'd out, but the admin servers is. I bet SIMS has something to answer there, but also things you might not think relevant, such as the amount of physical memory, impact on network usage.

Slow log on times could be down to the desktop applying GP, not the network.

Our DC's only ever get up to about 5% at most. Our file server reaches a maximum of 10% - 15% and the SIMS server around 5 - 10% also. Seems normal to me.

That seems soo weird though. Glad its the norm.

I always pictured the HDD's to be the problem, yet after a recent upgrade to 4GB RAM and More HDD storage that it may help the network.

I see students pulling publisher files 50mb+ for a lesson x 30 and you'd think thats when a GB backbone helps. I suppose the HDD's will always be the slowest part of a network.
