Всем привет
при нагрузке на канал виснет pptp подключение к инету, ну скажем при скачивании фильмов с торрентов на скорости 2-2,5 МБ/с
то есть скорость поднимается до этой отметки, держится около минуты и подключение "зависает" - отправка пакетов идет а приема нет, далее какое-то время система думает (видимо время зависит от lcp-echo-interval и lcp-echo-failure), подключение сбрасывается и устанавливается вновь.. через минуту падает опять.. и так пока не скачались фильмы.. сильно сомневаюсь что дело в провайдере, сегодня ночью еще поэкспериментирую на другом компе
так же при увеличении нагрузки на канал очень сильно увеличивается нагрузка на ЦП, хотя сейчас держится на уровне 5-7%, но бывает поднимается до 20-25% (шифрование?)
