It takes many hours for aarch64 to finish builds that it takes only one hour for ppc64le. Are there any tweaking ways to improve the build speed ?

With the current hardware we have there's not much we can do. The info about builder boxes is readable from hw_info.log in each build: https://copr-be.cloud.fedoraproject.org/results/tachoknight/swift-lang/fedor...

We have two hypervisors that are divided to 8 such builders.
