Bonding- No getting Full speed

Hi,

We have setup a Bonding VPN for a client. What we have is a 450G on each side, and a 750G in the middle.

At each office is a 450G with 2 High power wireless devices plugged in. ,and then in the middle there are 4 of the wireless devices, 2 to each office.

These devices plug into the ethers on the 450G’s.

What we have done is do a EoIP tunnel over the wireless devices, so its 2 tunnels per 450G. then we are bonding the EoIP tunnels with round robin.

See the diagram to get a visual layout.

now our problem is that even though the individual lines give us 35 meg/s each, the bonding does split the traffic, but we still only get 35 meg/s. It doesn’t use both lines to the max.

is there anything we are missing?

Can anybody give an idea?

what kind of traffic do you have? try bonding-xor instead of -rr

what CPU load?
