Tried an interesting experiment this morning where I built an #amd64/#arm64 #Docker image of Diaspora, which heretofore had always been just an amd64 image. Building this on an arm64 laptop meant that all the amd64 stuff took place in (quite slow) #qemu emulation. Here are the timings for the two builds, which #BuildKit runs in parallel. You can see the commands and architectures, and how long each took to run:
