Docker Desktop for Windows

I could not find this issue posted so I will post it .
I’ve just recently installed Docker and it is REALLY REALLY SLOW. When i mean slow, i mean it takes a few minutes to start up and executed any command is also painfully slow. Please see the following log extract to get an ideea:

It took 3 minutes for docker to respond to “docker info”.

Well, in case anyone bothers to read this, the cause of the problem seems to be related to a multitude of possible issues which may or may not be related.
First possible cause is the existance on my machine of a previously configured office VPN. Whenever i connect to the VPN then docker instantly becomes much faster.
Second possible cause is related to the fact that docker adds some entries in the “hosts” file which, i think may not be reached if connected/disconnected from VPN.

What I’ve also done is configured docker to work through WSL1 for Windows 10 with Ubuntu. Now it seems to work great even if i am or am not connected to the work VPN.
