I show also some numbers. This is the log of an action build running on a mac with 32 GB

On a recent Mac with 32GB it takes 71 seconds.
On a server with Linux and 64GB it takes 50s, on a Mac with 16gb it takes 10 minutes.

I cannot think of making the build simpler. It is only one step build, that download data
from a git repository and pushes a very thin layer on a docker registry. I cached the base
image with kaniko.

I am very seriously concerned about this situation.

Hello Whiskers,

I created a tekton build using a modified version of the actionloop runtime.

Code here:

I tried also to setup a cache for Kaniko and preload the image:

However when I try to build the image it takes a lot, really a lot of time. Several minutes,
often more than 10minutes.

The build executed with docker takes just a few seconds .

Anyone shares my experience with knative build speed? This is a serious problem because creating
an image is essential to be able to use knative serving.
