"Babel is not threaded, so multicore does nothing for it. But bumping the memory to 128 would probably be a good thing (edited)"

Is any process in OpenWRT firmware threaded?
Is any process in any AREDN firmware threaded?
Is any process improved by more than 1 CPU core in Proxmox/QEMU configuration?
Is any process in ARDEN firmware improved by the hAP ac2/3 having 4 cores?
