Yeah, no. To this day Firefox developers building Gecko need a beefy desktop machine to be able to do it in a reasonable amount of time. I could do a clean build in 6 minutes with a ThreadRipper whose cores were all pegged, but forget doing the same in under an hour on a laptop.

And that was with unified builds enabled.

And more importantly, on that same machine the build would take more than ten minutes without unified builds.
