The compiler can compile itself natively on a pi2 or pi3. No need to activate swap space, unless you want to run the full test suite. > Another option worth exploring may > be AOE as pi4 has a GbE (I haven't tried this yet). My go test builders are running with "local" fossil on a slice of disk provided over AoE from an atom server. I tried various configurations and this gave me the best performance. This is with 3B+ machines on "gigabit" ethernet throttled by rubbish usb. Pi4 has proper GbE, but also has usb3 so a local ssd drive might be a practical alternative. More experiments to do.
