What is most optimum configuration changes to improve performace

[Abhijit Kumar]

What is the best configuration parameter changes or tuning that we can do on OrientDB v3.03 running in distributed mode to improve performance. 

Our Orientdb schema consists of:

Vertex: Two types of Vertex, one with 16 properties and other with 9 properties

Edge: Two types of edge each with 3 properties.

I am currently using the default Orientdb configuration and there is a continuous stream of records that are getting added to OrientDB.
