Hi Norman, I used the WireShark to monitor the Traffic , when i measure the TCP_STREAM the tcp packet from the linux to rpi has small window size ( 229 ) while it is around (18000) from rpi to the Linux ,
is that the problem , should i try to change this value and what is the regulare value to use it ? best , 2014-11-04 3:57 GMT-08:00 Mohammad Hamad <[email protected]>: > 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?
