Another thoughts about this: a network analysis seems to show that the 
bottleneck is not in post-proxy handling, but upstream. We know that 
radperf is sending as much requests as we told him (with -p 500 
argument), but the rate of outgoing  proxied requests is far lower.

See the graphs above:

- rlm_lrs invoked in post-proxy section:

So, is it possible that FreeRadius slows down the proxied requests sent 
to the remote radius, for instance in order to be sure to have always 
enough available threads to deal with the responses ?

Note that our max_outstanding parameter is set to 4096. Should we care 
of other parameters in the proxy section ?
