repeat() query takes really long time

[monali01]

I have this issue open on SO

I am using most of the default configurations that came with it. Gremlin server on EC2 of t2.medium size. I have read and write capacities and rates set to 100 (also, set to 200, didn't seem to change any performance).
Total data is about 44,510

Making multiple requests were effecting time poorly, I am experimenting with storage.dynamodb.client.executor.max-concurrent-operations at this moment.

Overall, all other queries are very slow too.

Please refer to SO for details about sample data model and query.
