Merci. J’ai négligé d’installer la version 3 disponible en package sur le site iperf.fr et fait confiance aux repositories officiels dont elle est absente. La présence de la version 2 par défaut dans Debian est-elle du à une divergence de vues avec les développeurs ?
Après quelques tests vers des destinations extra-européennes j’aimerai les commentaires de ceux qui ont l’habitude de l'outil. Tous les tests ont été effectués depuis une interface Fast Ethernet. 1 - vis-à-vis du Kazakhstan (iperf.it-north.net) 1.1 en upload depuis la machine locale, TCP parvient à saturer l'interface iperf3 -fm -c iperf.it-north.net -p 5201 Connecting to host iperf.it-north.net, port 5201 [ 4] local 192.168.1.252 port 51830 connected to 82.200.209.194 port 5201 [ ID] Interval Transfer Bandwidth Retr Cwnd [ 4] 0.00-1.00 sec 3.52 MBytes 29.5 Mbits/sec 0 905 KBytes [ 4] 1.00-2.00 sec 11.6 MBytes 97.0 Mbits/sec 0 1.52 MBytes [ 4] 2.00-3.00 sec 11.2 MBytes 94.2 Mbits/sec 0 1.52 MBytes [ 4] 3.00-4.00 sec 11.2 MBytes 94.3 Mbits/sec 0 1.52 MBytes [ 4] 4.00-5.00 sec 11.2 MBytes 94.3 Mbits/sec 0 1.52 MBytes [ 4] 5.00-6.00 sec 11.2 MBytes 93.9 Mbits/sec 0 1.52 MBytes [ 4] 6.00-7.00 sec 11.2 MBytes 94.3 Mbits/sec 0 1.52 MBytes [ 4] 7.00-8.00 sec 11.2 MBytes 93.8 Mbits/sec 0 1.52 MBytes [ 4] 8.00-9.00 sec 11.2 MBytes 94.4 Mbits/sec 2 1.52 MBytes [ 4] 9.00-10.00 sec 11.2 MBytes 94.4 Mbits/sec 0 1.52 MBytes - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bandwidth Retr [ 4] 0.00-10.00 sec 105 MBytes 88.0 Mbits/sec 2 sender [ 4] 0.00-10.00 sec 102 MBytes 85.9 Mbits/sec receiver iperf Done. 1.2 en download, TCP est cappé à 2Mbits ! iperf3 -fm -R -c iperf.it-north.net -p 5201 Connecting to host iperf.it-north.net, port 5201 Reverse mode, remote host iperf.it-north.net is sending [ 4] local 192.168.1.252 port 51826 connected to 82.200.209.194 port 5201 [ ID] Interval Transfer Bandwidth [ 4] 0.00-1.00 sec 249 KBytes 2.04 Mbits/sec [ 4] 1.00-2.00 sec 277 KBytes 2.27 Mbits/sec [ 4] 2.00-3.00 sec 277 KBytes 2.27 Mbits/sec [ 4] 3.00-4.00 sec 286 KBytes 2.34 Mbits/sec [ 4] 4.00-5.00 sec 283 KBytes 2.32 Mbits/sec [ 4] 5.00-6.00 sec 274 KBytes 2.25 Mbits/sec [ 4] 6.00-7.00 sec 266 KBytes 2.18 Mbits/sec [ 4] 7.00-8.00 sec 286 KBytes 2.34 Mbits/sec [ 4] 8.00-9.00 sec 266 KBytes 2.18 Mbits/sec [ 4] 9.00-10.00 sec 280 KBytes 2.29 Mbits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bandwidth Retr [ 4] 0.00-10.00 sec 2.71 MBytes 2.28 Mbits/sec 0 sender [ 4] 0.00-10.00 sec 2.71 MBytes 2.28 Mbits/sec receiver iperf Done.
