Bridge throughput problem

Hi,

i have one Wireless link with two LHG 2,4ghz. Here is the concept:

Client <---- > LHG2 <----Wireless----> LHG1 <----Cable----> RB3011

LHG1 is in bridge mode.

When i do the bandwidth test between LHG2 and LHG1 i get 100MBIT TCP:

And when i do the bandwidth test between LHG2 and RB3011 i get arround 62MBIT TCP:

So i dont understand why i dont receive 100MBIT also? Where are this 30mbit lost? The lan connection is 100MBIT.

When im doing the bandwidth test i also dont see any packets flowing through BRIDGE interface. Is this normal?

Thanks.

I would say because generating data is using a lot of CPU cycles, which your APs are in short supply. Thus, lower throughput.
