Оно пытается вычитать с адреса "http://169.254.169.254/latest/meta-data/" сведения, это API метаданных амазона, в рядовом случае (то есть не будучи читано из облака) оно не отвечает, и так 10 минут, после чего выдает уже сведения всякие. Это из виртуалки, с машины в локальной сети все выдается быстро и по этому адресу не обращается.

Смысл в том, что этот бисер определяет, что он запущен внутри виртуалки и считает, что он внутри ec2 (т.е. облака амазона), после чего обращается по тому адресу. Я могу уменьшить просто в спеке таймаут с доступом по ому адрему, до полутора секунд, чтобы не тормозил.
