Why has a VM using NAT a 3 x faster DL speed then using Bridged mode?

[InvisibleMan78]

Today I found some strange behaviour.
After setting up a new VM for the newest version of MB Docker I accidentally set the VM network connection to NAT (=Network Address Translation) instead of Bridged. I got a 192.168.232.130 instead of the usual 192.168.1.123 IP address. My host PC has 192.168.1.111.

During the download of the newest data dumps I realized that the DL speed with NAT was 3 x faster then the usual DL speed using Briged mode.

How can that be?

(I’m aware that the DL speed also depends from the source, but I don’t believe that the difference can be that big).

So far I was believing that the Bridged network Mode should be much faster.

Any ideas?

I don’t know if there is any big difference with NAT/Bridged but the difference with the source is up to 10x.
