Especially since you're running off a cronically slow USB port. As
noted on the spec and description the ports are USB2 but only run a
USB1.1 speeds.
Native compiling is only really sensible for small test programs not
major pkgs like cutie.
Yan you may do better building with Os, it optimises for small
systems, it's O2 without a couple of space hungry speed ups. It is
highly debatable where O3 is faster than O2 on a desktop machine but
it will be far too bloated for embedded. Several of the O3
"optimisations" are horribly wasteful of space to gain microscopic
speed ups.
Hope I understood what you meant.
