Gitlab Runner on AWS becomes really slow after some time
Solution 1:
Had the same issue, pipelines timed out after an hour while usually taking ~8mins. Stopped the EKS node EC2 instance in AWS Console (t3.small). (the one that the runner was created on) The Autoscaling group took over, brought up a new node and killed the old one. The pipelines came back to normal speed. Will be looking to increase instance size in the future.
