I'm the author of graph-tool, so my opinion may be biased. :-)

Nevertheless, I do think that graph-tool will be faster and have a
smaller memory footprint than networkx, since the graph data structures
and most algorithms are written in C++, using the Boost Graph Library,
whereas networkx is mostly pure python. I have made this library due to
my own requirements of being able to work with large graphs.

The only other library I can think of which may be comparable in
performance is igraph, which is implemented in C. But I think
graph-tool's interface is a bit more polished (my opinion
only). Moreover, since graph-tool uses template metaprograming to obtain
specialized versions of algorithms, it may be that it is even faster
than igraph, but I have at the moment no benchmarks to back this up.

Cheers,
Tiago
