NLB poor network performance

Hello Ng.

We are using Application center on 3 web servers for web applications.

The servers are Windows 2003 with App Center 2000 SP2.
We are running on a T3 line and on our DMZ we have a few more servers both Windows and Linux.

When I am trying to DL from the Web farm cluster members I get speeds between 1,2 - 7.10 MB/s but no more.
Sometimes it will be low on 1,2-2,2 mbps for hours.

When I am trying to download from other servers on the DMZ I get never speed under 8mbps.

The NLB is set up with one cluster IP address
Cluster Operation Mode : Unicast
NLB Client Afinity : Internet Class C (We have tried also with single afinity) same result.

The cluster network adapters are connected to a 100mb hub and from there to our DMZ switch.

Any ideea why this poor network performance and how can we improove it ??
