Good to know! I was doing this with a hacky one-liner but wasn't aware of this flag. I think the sequential build/install process is the agonizing bit though.

Yeah I don’t know how people are saying it’s slow. If you have 5000 packages installed maybe?
If your version is 5.0.0 or newer, concurrency is already active by default.
