Hi, I am assuming you are already using multiple build agents <https://www.jenkins.io/doc/book/scaling/architecting-for-scale/#distributed-builds-architecture> .
Jenkins OSS does not support horizontal scaling of controllers. CloudBees CI is the only option I know of that supports horizontally scaling controllers. https://www.cloudbees.com/blog/revolutionize-your-jenkins-environment-with-ha-hs Other than that so you know where your memory is going? Pipeline groovy will consume memory on the controller, so performing things like json /yaml processing in groovy Rather than as a shell step can be a factor limiting scalability.
