RAM usage of building a system image

My script that is building a system image needs about 32 - 50 GB of RAM. This is very expensive. I am trying to use a swap file, but this is getting very slow. See for example: Install KiteModels#main · OpenSourceAWE/AWEMeta.jl@2a4ca15 · GitHub Not sure if this job will finish within 4h. Any ideas how to reduce the RAM usage? I switched from ControlPlots.jl to MakieControlPlots.jl. Before it was kind of OK. You can find the script that builds the system image here:
