Тестирование скорости сервера в Linux Ubuntu

Заметил, что скорость на сервере все время маленькая - почему-то не превышает 10 Мбит/с, в то время, как должна достигать 100 МБит/с. Долго думал, что это из-за того, что у пользователей маленькая скорость, но... Вот у меня локальный интернет 80МБит/с и скорость все настолько же низкая: 0,8-2Мбит/с.

Начал искать причину. Протестировал локальный интернет на своем компьюетере с помощью сайта http://www.speedtest.net/.

Показатели, конечно, меньше 80МБит/с, но в целом - выше на порядок, чем между сервером и локальным компьютером: 20-40Мбит/с...

Как же протестировать сервер ?

Как оказалась, есть такая замечательная команда iperf.

Устанавливаем iperf на сервере:

apt-get install iperf

На клиентском компьютере, если он под Linux выполняем тоже данную команду. В случае же Windows ставим версию для Винды:

http://iperf.ru/wp-content/uploads/2009/07/jperf-2.0.0.zip

Теперь, запускаем на сервере сервис:

iperf -s

Выполняем на клиенте:

iperf -c НазваниеВашегоСервера -P 20

Расшифровка ключей.

-с - указывает на компьютер с которым происходит передача данными.

-P - указывает на количество потоков, которые используются при передаче данных (в нашем случае - 20 потоков).
