К вопросу о скорости (замедлении) при использовании TOR-прокси...
К скорости...
На клиенте работает TOR-стек:

На сервере (за 4000 км) запускаю iperf3 на открытый брандмауэром порт:

Всё верно - 50 Mbits/sec это скорость, которую я оплачиваю своему
провайдеру 
P.S. Со стороны сервера хостер обеспечивает:

На сервере iperf3 при этом мы видим для 2-х случаев картины:

Вряд ли скорость 1.31 Mbits/sec здесь можно соотносить хоть как-то со скоростью канала 50 Mbits/sec - она будет у разных клиентов в разной геолокации на такой цепочке...
