Here you go - all pretty straightforward:
https://gist.github.com/mpollmeier/108ab8998e3b0321f020
Without a bulk api for neo4j it takes nearly 70s to create 30k vertices.
There is currently no publicly available build artifact of tinkerpop3
that contains neo4j-gremlin, so this all depends on custom local builds.
The main thing is the obvious stuff I guess: disable indexes and
integrity constraints. Should be the same as the good old
Neo4jBatchGraph, no?
https://github.com/tinkerpop/blueprints/tree/master/blueprints-neo4j-graph/src/main/java/com/tinkerpop/blueprints/impls/neo4j/batch
I guess for license reasons we can't just copy that but have to
reimplement it?
Cheers

Michael,
If there are any areas that can be sped up in the Neo4jGraph codebase, please
identify. There hasn't been much manual testing of Neo4jGraph so any
help/tickets/PRs you could provide would be greatly appreciated.
Also, could you share your data loading code via a gist?
Thanks,
Marko.

General support for bulk loading is still under development and won't be
available for GA. Here's some related issues:

https://issues.apache.org/jira/browse/TINKERPOP3-550
As for just straight loading, I'm not sure we've evaluated performance of
neo4j-gremlin at this point. Not sure what improvements are to be had, if any.

What's the best way to insert many elements at the same time, is there some
sort of bulk mode that doesn't check for constraints? I didn't find anything
fitting in the code/documentation in TP3.
Creating 25k vertices takes around 40s, and about 50s if I wrap it in a
transaction - that's a bit slow.
