slow network

Hello All,

Since we had this problem with the DE500 network card,
The system is going slow, relatively, slower than it was before.
I can see Collisions and Output errors, but I can't get my hand on the
problem.
Any one saw this before, I guess so!, please help
The system is 4100 running True64 V 4.0D network card is DE500
100MB/full duplex (Some mentioned before that full duplex doesn't act
well, but it was fine before)

Output from command netstat -in (ommiting the address colomn) :
Name Mtu Network Ipkts Ierrs Opkts Oerrs Coll

The /etc/rc.config file has the following entries:
RWHOD=
ROUTED="no"
ROUTED_FLAGS=""
ROUTER="no"
GATED=
GATED_FLAGS=
GATED=
GATED_FLAGS=

You can see the collisions and Output errors as well as the send
failures. Could this mean that the network is congested?, the card is
bad?, or the system is missing something?

Waiting for your great replies

TIA
