Orientdb performance issue on multi-threaded system

问题

When you go through OrientDb website, they give some fancy statistics about number of document than can be created per second.

I am not in need of any these fancy speed, a moderate will work for my use case.

My use case :

• My system is multi-threaded

• On per request I am receiving

  • Db-Name
  • Current_Vertex_Name
  • Previous_Vertex_Name

• Then execute the below pseudo code :-

I did tried my use-case with the below pseudo code but I found speed very slow.

Pseudo code of my use case is following below:-

        DB_Name = getFromSource()

        createGraphDb(DB_Name ) using OServerAdmin : if db do not exist
        gFactory = OrientGraphFactory(DB_Name ) : if db exist


        graph = OrientGraphFactory.getTx()

            currentVertexName = getFromSource()
            previousVertexName = getFromSource()

            if(previousVertexName and currentVertexName != null)
                  {
                       - if not exist 
                             - create Vertex named 'currentVertexName' , 'previousVertexName' 
                       - else
                             - update the existing vertexes e.g "update counter"
                       - create edges between them(from previous to current event)
                  }                 

       graph.shutdown()

Can any one, please share Java code creating at-least 1k Vertex + edges per second..!

Thanks..!
