bandwidth issue when repeating with nstreme2

RouterOS General
1

What is the effect on bandwidth of creating two separate links as in a scenario where a repeater is involved.
ie:
a to b via nstreme2
b connected to c via a 100Mb/s switch
b to c via nstreme2.

Using g turbo on atheros AR5213’s i get 24Mb/s from a to b and the same from c to d.
As soon as i test from a to d is only get 1/2 or 12MB/s.

Is this normal for nstreme2 ?
I am of the understanding that nstreme2 operates similar full duplex where you can have lots of hops (repeaters) without losing too much bandwidth.

Any help would be greatly appreciated.

If in B you have, only one board and two minipci the issue could be related to the cpu utilizzation.

We tried combining b and c on a four port pci to mini pci adaptor card - 3.0Ghz P4 512Mb Ram 20Gb HDD. We have the same results. Anyone prepared to help consult with the problem - prepared to pay for assistance.

We need to bounce the signal 20Km from the source to a repeater with relays it another 40Km to the client.

Something like that can be seen in nstreme1 repeated links
