Правильное измерение скорости
Для измерения скорости используем iperf3, версию 3.1.3 для Windows 64 можно взять здесь.
Распаковываем в текущую папку пользователя, в данном случае это C:\Users\1>
Серверная часть
На стороне, которая будет сервером, набираем в консоли .\iperf3.exe -s, и жмем разрешить доступ в брандмауере Windows:
Ключом -p можно указать конкретный порт, который будет слушать сервер iperf3:
PS C:\Users\1> .\iperf3.exe -s -p 5001 ----------------------------------------------------------- Server listening on 5001 -----------------------------------------------------------
Клиентская часть
Со стороны клиента также распаковываем соответствующие файлы в папку текущего пользователя. Для подключения к серверу указываем его адрес, ключ определяющий клиента -с, и ключ указывающий порт -p. Клиент в это случае скачивает с сервера произвольные данные, для большинства случаев этого достаточно:
PS C:\Users\1> .\iperf3.exe -c 192.168.88.214 -p 5001 Connecting to host 192.168.88.214, port 5001 [ 4] local 192.168.88.250 port 1134 connected to 192.168.88.214 port 5001 [ ID] Interval Transfer Bandwidth [ 4] 0.00-1.01 sec 110 MBytes 911 Mbits/sec [ 4] 1.01-2.00 sec 108 MBytes 916 Mbits/sec [ 4] 2.00-3.00 sec 112 MBytes 943 Mbits/sec [ 4] 3.00-4.00 sec 102 MBytes 851 Mbits/sec [ 4] 4.00-5.00 sec 91.6 MBytes 769 Mbits/sec [ 4] 5.00-6.00 sec 61.1 MBytes 513 Mbits/sec [ 4] 6.00-7.00 sec 94.5 MBytes 792 Mbits/sec [ 4] 7.00-8.00 sec 104 MBytes 871 Mbits/sec [ 4] 8.00-9.00 sec 100 MBytes 844 Mbits/sec [ 4] 9.00-10.00 sec 92.1 MBytes 773 Mbits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bandwidth [ 4] 0.00-10.00 sec 975 MBytes 818 Mbits/sec sender [ 4] 0.00-10.00 sec 975 MBytes 818 Mbits/sec receiver iperf Done.
Для тестирования обратного направления используем ключ -R или —reverse, при этом клиент закачивает произвольные данные на сервер:
PS C:\Users\1> .\iperf3.exe -c 192.168.88.214 -R -p 5001 Connecting to host 192.168.88.214, port 5001 Reverse mode, remote host 192.168.88.214 is sending [ 4] local 192.168.88.250 port 1153 connected to 192.168.88.214 port 5001 [ ID] Interval Transfer Bandwidth [ 4] 0.00-1.00 sec 112 MBytes 937 Mbits/sec [ 4] 1.00-2.00 sec 112 MBytes 935 Mbits/sec [ 4] 2.00-3.00 sec 113 MBytes 949 Mbits/sec [ 4] 3.00-4.00 sec 104 MBytes 875 Mbits/sec [ 4] 4.00-5.00 sec 113 MBytes 945 Mbits/sec [ 4] 5.00-6.00 sec 111 MBytes 931 Mbits/sec [ 4] 6.00-7.00 sec 113 MBytes 947 Mbits/sec [ 4] 7.00-8.00 sec 112 MBytes 938 Mbits/sec [ 4] 8.00-9.00 sec 110 MBytes 927 Mbits/sec [ 4] 9.00-10.00 sec 111 MBytes 931 Mbits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bandwidth [ 4] 0.00-10.00 sec 1.08 GBytes 932 Mbits/sec sender [ 4] 0.00-10.00 sec 1.08 GBytes 932 Mbits/sec receiver iperf Done.
Ключом -t можно задать длительность теста, например 5 секунд:
PS C:\Users\1> .\iperf3.exe -c 192.168.88.214 -t 5 -p 5001 Connecting to host 192.168.88.214, port 5001 [ 4] local 192.168.88.250 port 1246 connected to 192.168.88.214 port 5001 [ ID] Interval Transfer Bandwidth [ 4] 0.00-1.00 sec 111 MBytes 932 Mbits/sec [ 4] 1.00-2.00 sec 112 MBytes 943 Mbits/sec [ 4] 2.00-3.00 sec 104 MBytes 874 Mbits/sec [ 4] 3.00-4.00 sec 110 MBytes 919 Mbits/sec [ 4] 4.00-5.00 sec 113 MBytes 945 Mbits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bandwidth [ 4] 0.00-5.00 sec 550 MBytes 923 Mbits/sec sender [ 4] 0.00-5.00 sec 550 MBytes 923 Mbits/sec receiver iperf Done.
Ключом -P задаем количество генерируемых потоков, например 5 потоков позволяет сгенерировать больший трафик в канале:
PS C:\Users\1> .\iperf3.exe -c 192.168.88.214 -t 5 -P 5 -p 5001 Connecting to host 192.168.88.214, port 5001 [ 4] local 192.168.88.250 port 1263 connected to 192.168.88.214 port 5001 [ 6] local 192.168.88.250 port 1264 connected to 192.168.88.214 port 5001 [ 8] local 192.168.88.250 port 1265 connected to 192.168.88.214 port 5001 [ 10] local 192.168.88.250 port 1266 connected to 192.168.88.214 port 5001 [ 12] local 192.168.88.250 port 1267 connected to 192.168.88.214 port 5001 [ ID] Interval Transfer Bandwidth [ 4] 0.00-1.00 sec 23.5 MBytes 197 Mbits/sec [ 6] 0.00-1.00 sec 22.5 MBytes 189 Mbits/sec [ 8] 0.00-1.00 sec 22.0 MBytes 184 Mbits/sec [ 10] 0.00-1.00 sec 22.5 MBytes 189 Mbits/sec [ 12] 0.00-1.00 sec 23.0 MBytes 193 Mbits/sec [SUM] 0.00-1.00 sec 114 MBytes 951 Mbits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ 4] 1.00-2.00 sec 23.4 MBytes 196 Mbits/sec [ 6] 1.00-2.00 sec 22.1 MBytes 186 Mbits/sec [ 8] 1.00-2.00 sec 22.5 MBytes 189 Mbits/sec [ 10] 1.00-2.00 sec 22.4 MBytes 188 Mbits/sec [ 12] 1.00-2.00 sec 22.6 MBytes 190 Mbits/sec [SUM] 1.00-2.00 sec 113 MBytes 948 Mbits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ 4] 2.00-3.00 sec 23.4 MBytes 196 Mbits/sec [ 6] 2.00-3.00 sec 22.2 MBytes 187 Mbits/sec [ 8] 2.00-3.00 sec 22.2 MBytes 187 Mbits/sec [ 10] 2.00-3.00 sec 22.5 MBytes 189 Mbits/sec [ 12] 2.00-3.00 sec 22.8 MBytes 191 Mbits/sec [SUM] 2.00-3.00 sec 113 MBytes 949 Mbits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ 4] 3.00-4.00 sec 23.0 MBytes 193 Mbits/sec [ 6] 3.00-4.00 sec 20.8 MBytes 174 Mbits/sec [ 8] 3.00-4.00 sec 21.9 MBytes 183 Mbits/sec [ 10] 3.00-4.00 sec 21.8 MBytes 182 Mbits/sec [ 12] 3.00-4.00 sec 22.9 MBytes 192 Mbits/sec [SUM] 3.00-4.00 sec 110 MBytes 925 Mbits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ 4] 4.00-5.00 sec 23.8 MBytes 199 Mbits/sec [ 6] 4.00-5.00 sec 22.1 MBytes 186 Mbits/sec [ 8] 4.00-5.00 sec 22.6 MBytes 190 Mbits/sec [ 10] 4.00-5.00 sec 21.9 MBytes 183 Mbits/sec [ 12] 4.00-5.00 sec 23.0 MBytes 193 Mbits/sec [SUM] 4.00-5.00 sec 113 MBytes 951 Mbits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bandwidth [ 4] 0.00-5.00 sec 117 MBytes 196 Mbits/sec sender [ 4] 0.00-5.00 sec 117 MBytes 196 Mbits/sec receiver [ 6] 0.00-5.00 sec 110 MBytes 184 Mbits/sec sender [ 6] 0.00-5.00 sec 110 MBytes 184 Mbits/sec receiver [ 8] 0.00-5.00 sec 111 MBytes 187 Mbits/sec sender [ 8] 0.00-5.00 sec 111 MBytes 187 Mbits/sec receiver [ 10] 0.00-5.00 sec 111 MBytes 186 Mbits/sec sender [ 10] 0.00-5.00 sec 111 MBytes 186 Mbits/sec receiver [ 12] 0.00-5.00 sec 114 MBytes 192 Mbits/sec sender [ 12] 0.00-5.00 sec 114 MBytes 192 Mbits/sec receiver [SUM] 0.00-5.00 sec 563 MBytes 945 Mbits/sec sender [SUM] 0.00-5.00 sec 563 MBytes 945 Mbits/sec receiver iperf Done.
