SMP: AP CPU #1 Launched!
В неё воткнуты один внутренний канал в локалку и 4 наружних канала:
Украина+мир от основного аплинка (оптика), и два резервных. На машинке
поднята quagga - ловит украинский трафик и направляет в нужный канал.
Все сетевухи - em, fxp (для резервных каналов). Активных пользователей
тырнета - порядка 300 человек в единицу времени. Недавно провайдер
поднял скорость каналов, но выше 150-200 Мб/с добиться пока не
удалось. Попытка прокачать большой файлик по внутреннему каналу
показывает максимальную скорость больше 400 Мб/с. Загрузка сиситемы по
top-у в момент тестирования не превышала 40%. Провайдер утверждает,
что у него всё в порядке и рекомендует поменять железо. Поскажите, что
можно покрутить, ещё чтоб увеличить скорость работы. Железо предлагают
поменять на i7 и систему заменить на х64, но я не уверен, что станет
лучше. Готов предоставить любую дополнительную информацию.
