If those are serialized String objects then I'm seeing the following
mismatch between measurement and calculation:
The graph I'm using has 4.9 million nodes, each of which has 40 string
properties (each of which has 16 characters). It has 70 million directed
edges, each of which has 1 string prop

Great, thanks :)

Yes and yes.

What Chris said

also disable the node and relationship autoindexes you most likely don't need
them.
You should also probably upgrade to M02 or use 2.2.3 (stable).
And you might set in neo4j.properties
keep_logical_
not sure what it expects.
for recent versions of Neo4j you'd change that to:
(Don't you also need id's for the source and target?)
MATCH (x:Person)-[:DIRECTED]->(m) return x.name, n.title
Not sure what it expects as edge query, usually it is the source and target
id's plus edge properties or t
Pat,
for console.neo4j.org I create in-memory graph databases (and put them into
each users web-session) using the ImpermanentGraphDatabase for
org.neo4j:neo4j-kernel:test-jar package.
That works pretty well. It is still acid but uses an virtual, in-memory FS.

I have a small graph with approximately 1000 vertices and 5000 edges, and
perhaps 100 properties at each vertex.
The graph only needs to be readable - I have no write requirements and I
don't care about integrity or ACID etc.
I'd like to embed the graph in my program (preferably scala but java
