docker build starting slow

I'm testing docker builds on two different systems. Ubuntu and Arch linux. I'm experiencing significant slow docker build starting speeds (same Dockerfile) on Arch linux (better/newer machine).

In both systems Docker version 20.10.12 Storage Driver: overlay2

Further investigations shows that there is no delay between creation of layers. Initial time to start the build is the culprit

It was the additional DNS lookup's causing the start delay. Removing the extra mirrors from .docker/config.json did the trick

cat .docker/config.json 
{
  "credHelpers": {
    "asia.gcr.io": "gcloud"
  }
}
