Why is latency smaller when running website from localhost?

Question

When i “ping” a hostname from my remote website the latency is larger than when I ping the same hostname from localhost (or using the ping command). I use the same machine for both tests. Why is this happening?

Answer 1

Because the network is zero length instead of possibly 12,500 miles, or much more in the case of satellite links, and consists of zero routers instead of possibly dozens.
