What backing store are you using? Also are you running Janus embedded or does your client hit gremlin server remotely? I'll assume you're using Cassandra just to give you a few things to check but these should be generally applicable. First I'd see where the slowdown is coming from. My guess would be the Janus IO with its backing store but you never know, it could be as simple as bumping up a heap size on your client. Here are a few things to watch as your run your load:
* Client (and janus server if it's running separate from the client) & Cassandra GC stats (GC counts & latencies)
* Cassandra (or other backing store) read & write latencies
If you see the increase coming from the backing store I'd recommend following the tuning tips appropriate for your backing store to see if you can stabilize that performance to a point you feel comfortable. Also, if this is a POC, be sure to test on hardware that is representative of what you'd actually be using in production. If it's just your laptop, I'd take any performance learnings with a grain of salt. A single laptop setup is not a good proxy for production performance against a distributed backend.
