NLB and slow access speeds

I have two Windows 2003 Servers setup in a network load balanced setup for
http and https. I set this systems up according to the standards I have found
online and recommendations from an external company, but I have noticed that
copying files to or from this system is incredibly slow. Each system is a
Dell PowerEdge 1950 server with two Broadcomm 57xx NICs onboard:

System 1
NIC 1 - 10.251.1.181
255.255.0.0
10.251.1.254
NIC 2 - 10.100.1.1
255.255.255.252
no default gateway

System 2
NIC 1 - 10.251.1.182
255.255.0.0
10.251.1.254
NIC 2 - 10.100.1.2
255.255.255.252
no defalut gateway

Load Balanced Address for http/https - 10.251.1.180, 255.255.0.0, 10.251.1.254

Each NIC 1 is plugged into the main switch, each nic 2 is connected to the
other nic 2 via cross over connection. Apparently this is to provide access
between the two systems.

The switches are 1 GBPS switches and each NIC shows connected at 1 Gbps. To
give you an idea on the speeds, I am trying to copy the service pack 2 for
2003 from a system on the same switch and it is taking over an hour. To a non
nlb server connected to the same switch, less than two minutes.

Has anyone seen this before?
