It's not just the speed, it's the latency. I noticed usb2-connected
devices were a bit faster but the latency was high, particularly
with smaller reads/writes. There may be other issues, but this is the
thing that was noticed the most. I can't say I know the exact *why*
performance was better via ethernet; it just was.

for example, I had issues downloading the ports tree with git.
It would overrun frequently. The issue went away with nfs served
by a relatively fast system, running the update in the armv7 env.

Thing is, media r/w is a fundamental function. If those queue
past a certain point (which I'd imagine varies depending on what
the system is doing), stuff crashes weirdly.

I've not run freebsd on armv7 for a little while, but when I did,
the following were nfs-mounted:
           /usr/ports
           /usr/src
           /usr/obj
           /var/cache/ccache

I have a spare rpi2b if you want me to test this again.
What were you building to make it run out of memory?
