I've revied ron minnich's network performance problems on the
mail archive, and they are the same ones which we've been having
for some six months...

I have two of the alpha's isolted on a 100Mb switch, with
the switched foreced into FDX for its ports.

I have set the SRM's for both of the machines to 

    >>>set ewa0_mode FastFD
    Change mode to FAST Full Duplex.

I have checked:

    alpha1# cat /etc/ifconfig.de0
    192.168.129.1 netmask 0xfffff800 media 100basetx-fdx

And

    alpha2# cat /etc/ifconfig.de0
    192.168.130.1 netmask 0xfffff800 media 100basetx-fdx

I have verified visually that each of the cards are in 100,
and that each of the cards:

	
    alpha1# ifconfig de0
    de0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	    media: Ethernet 100baseTX full-duplex
	    status: active
	    inet 192.168.129.1 netmask 0xfffff800 broadcast 192.168.135.255
    alpha1# 

and

    alpha2# ifconfig de0
    de0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	    media: Ethernet 100baseTX full-duplex
	    status: active
	    inet 192.168.130.1 netmask 0xfffff800 broadcast 192.168.135.255
    alpha2# 


and yet:

alpha2# netstat -i
Name  Mtu   Network       Address              Ipkts Ierrs    Opkts Oerrs  Coll
de0   1500  <Link>        00:00:f8:1f:89:76     1731     8     1519     9    24
de0   1500  192.168.128/2 alpha2                1731     8     1519     9    24


Can someone explain to my what's wrong?
