CI/CD on AWS extremely slow

Hi,

So I've configured CodePipeline: connection to GitHub, CodeBuild (builds a Docker image and pushes it to ECR), and deployment using Amazon ECS on a Fargate cluster via service with task number = 1, minimum healthy=50%, maximum healthy=140%.

It takes astonishing 8 minutes(!) to build and push a simple container, also from the logs it is obvious the Docker layer cache is not used. And then the deployment stage takes ~10 minutes.

This is unreal. Is it supposed to be that slow? Are there any ways to make it faster?

Thank you.
