Network latency question on ssh tunnel

we have web server (my-service.com) running on a docker container, this
docker runs inside amazon EC2 instance.

my-service.com 用 some-service.com 的api, (which is not hosted on aws but on-premise)
there's a ssh tunnel between them.

从 EC2 linux shell,
curl -o /dev/null -s -w '%{time_total} s' https://some-service.com
大约 20 ms.

if do the same command from docker, 要他妈的 500 ms.

Q1: this big 500 ms delay, 是 ssh tunneling 引起的吗 ?
Q2: 如何改进 ?

多谢！

你这个问题应该去问john hennesey（ computer architecture 作者）,james gosling 谁的。
这么大的问题，说错了丢人怎么办。they don't giwashit，别人谁还敢放生。
