[Bug 894608] Re: Implementing a bridge slows 10G network

[Mike Imelfort]

Thanks for getting back to me.

Here is brctl show output:

$ brctl show
bridge name	bridge id		STP enabled	interfaces
br0		8000.0010187ee074	no		eth4

and ip link:

$ ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000
    link/ether f0:4d:a2:3b:9a:9e brd ff:ff:ff:ff:ff:ff

    link/ether 00:10:18:7e:e0:76 brd ff:ff:ff:ff:ff:ff
8: br0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN 
    link/ether 00:10:18:7e:e0:74 brd ff:ff:ff:ff:ff:ff

Also:

"Several sources suggest that turning odd tso, and perhaps also sg and
tx, might help. Could you try"

Tried this but it made no noticeable difference.

Thanks for your help so far.
