Hey Jason, It's an Asus laptop with a dual core Celeron N2830 CPU @ 2.16
GHz.  It was very low end - got it in 2015 from Micro Center for something
like $170 or $180 (maybe even less - can't remember exactly).  I am indeed
feeding maps to Xastir running on the same machine.  With the web server
running on the same machine it's just a matter of using a geo file in the
same format of the online OSM maps that points to the localhost instead of
a remote web server.

I'm not sure I fully understand that question, but I think it's
compute-bound.

I've been looking for a more powerful Pi alternative, and it seems the
reviews of a lot of them cite a lack of stability.  Good to know the Odroid
XU4 has been solid for you.
