Hi Norman , I just moved this morning to the current master branch and i got the same bad result for the throughput (between 2 and 6 10^6 bits/sec)
I will try the wireshark to monitor the traffics and try to find the problem. i will keep you updated. best, 2014-11-04 11:58 GMT+01:00 Norman Feske <[email protected]>: > Hello Mohammad, > > could you please switch to the current master branch?
