Re: Performance issues on a laptop.

I've just managed to connect to my standalone Cassandra 3.11 and can work from the gremlin shell with no visible hit on the CPUs, so I'm happy with that. In the past, I think I've missed the notice about running "nodetool enablethrift" and would get a error regarding AstyanaxStoreManager.

This the setup I need going forward anyway as I plan to websocket into gremlin server from microservices. 

I still have no idea why running janusgrah.sh causes it's cassandra to go berserk.

Maybe search to see if there's a known issue with running Cassandra on a MacBook. You could upgrade Cassandra if that's what you need. I believe JanusGraph is known to work with all current versions.

As soon as I killed the cassandra process, the CPU usage plummeted. So at least I know who the culprit was. I'll just start Gremlin Server directly (configured to us BDB), instead of using JanusGraph.sh.

For how long does the cpu remain high after you get the `gremlin>` prompt?

Hi, 

I'm trying to get JanusGraph running on my laptop (MacBook Air 2 Core Intel i7, 8GB) so that I can develop a small working prototype. 

I've gone for the janusgraph.sh method of starting the server and everything is fine until I open a gremlin shell. Then I see the CPU usage for my terminal rocket up past 350%. Once I close the gremlin shell, the CPU usage remains at the same high level, indefinitely. I've tried launching with the Berkeley DB option and no Elastic Search, but I get the exact same behaviour. 

Is there something I can do to stop this from using most of my CPU, or do I just have to live with it? 

Is there a "lite" recommended setup that someone has had success with in the past? 

Thanks.
