Optimize build performance on Jenkins Azure worker nodes

Today we focus on some performance optimizations for the Jenkins worker nodes on Azure instead of security as in the last blog post. -> https://www.danielstechblog.io/secure-jenkins-worker-nodes-on-azure/ As you might know already each Azure VM gets an additional SSD-based temporary drive beside the OS disk drive. Per default the swap file is stored on this temporary drive, because it is ephemeral. So, Read more [...]
