No Queue is set up on boxes.
I`m using WDS, as simple client interface is not bridgable.
If I switch to Nstreme can I bridge that interface too?
Will it eat less CPU power than WDS?
No, it will use much more cpu.. i had a similar situation, with the link loosing packets, i solved by enabling nstream.
The link now can easily do 6 mbps full duplex (and a peak of 12 mbps when just one side of the link is in use..)
I cannot tell you at this time how many pps the link manages (at this time is at it's lowest usage, and is doing about 700 pps on each side, and an average of 2.5 mbps each side)
Cpu load is, at this time, with nstream enable, at a slightly more than 50%
Most traffic is p2p, and this is a backhaul link that ends on the fiber connection to the internet.
User number is around 200 users for us too, but not all users are generating traffic at this moment.
I think you have already disabled what you could do to reduce cpu load, the only difference between your setup and mine is we use cm9 and that i do not use the same rb to handle the traffic betwen site one and three.
i.e. i would suggest you to split the middle RB in two RB, each with one radio card, and connected through the ethernet.
Using the RB to receive and re-launch the data through wireless can really kill its cpu.
You should be able to bridge them anyway
