Wondering ways to maybe improve time to build of my Pipeline?

[Deleted user]

I've customized the default Atlassian Dockerfile to create a custom image. I added the git-ftp installation as well as Gulp installation in hopes of cutting down on the Pipeline time.

Builds are taking just as long as before, but all the time is during the Build Setup. Is there a way to configure the image or the pipeline so the installations don't run from scratch during the Build Setup every time my pipeline runs?
