> We should investigate and try to bring the build time down.
> Some initial thoughts:
> - MR module build time dominates (1/3 of build time); we should check what is
> done there, is it necessary and can something (e.g. tests) be parallelized
> - There are few large artifacts produced and deployed/published by this build
> job; we should check if all of them are really necessary, and for necessary
> ones if we can reduce the artifact size to make publishing and build faster
