squirrel distributables built with on linux extremely slow

I have a problem regarding the build of my electron application. I try to build my apps with Jenkins so this is installed on a Linux system with mono. To build the application takes 50 to 65 minutes. That is not really usable.

I have read some things with asar and set that to “false”.

Making for the following targets:

On that point it stuck now for 60 minutes. That is not really good and not really usable.

No one an idea how to make it a bit fast? We need 1 hour for a build.

Same issue building on OSX, even with asar enabled, as I have a large amount of additional binaries/libs I need to include with the app. A full build takes an hour and a half 😦
