Как видим, скорость передачи данных через локальный виртуальный интерфейс просто гигантская. Пробуем, как передаются данные между Windows и установленной FreeBSD, через VmWare, безо всяких побочных эффектов (NeTAMS и модуль ядра выключены):

Естественно, медленнее. Теперь запустим NeTAMS и модуль ядра вместе, в режиме divert и убедимся, что это была не подстава:
