titan - performannce tuning in local dynamodb of titangraph -

thank reading this

my system configuration follows

processor : intel® pentium(r) cpu g2020 @ 2.90ghz × 2

o.s : ubuntu 16.04 lts

o.s type : 64-bit

r.a.m : 5.5 gib

i have use titan 1.0.0 gremlin query 3.0.1-incubating. have code defines child count of having 10000 verticex created binary tree having edges

code ->

`

baseconfiguration conf = new baseconfiguration();

    conf.setproperty("storage.backend", "com.amazon.titan.diskstorage.dynamodb.dynamodbstoremanager");     conf.setproperty("storage.dynamodb.client.endpoint", "http://localhost:4567");     conf.setproperty("storage.batch-loading ", "true");     conf.setproperty("storage.buffer-size", "10000");      conf.setproperty("query.fast-property", "true");             conf.setproperty("storage.buffer-size","65536");      conf.setproperty("cache.db-cache", "true");      conf.setproperty("cache.db-cache-time ","50");                   conf.setproperty("cache.db-cache-size ","0.15");      conf.setproperty("storage.directory","/tmp/foo");     conf.setproperty("index.search.backend", "elasticsearch");     conf.setproperty("index.search.directory", "/tmp/searchindex");     conf.setproperty("index.search.elasticsearch.client-only", "false");     conf.setproperty("index.search.elasticsearch.local-mode", "true");       long q = system.currenttimemillis();      titangraph graph = titanfactory.open(conf);      system.out.println("titan graph open");      system.out.println("time= "+ (system.currenttimemillis()-q));      titanmanagement mgmt = graph.openmanagement();      system.out.println(graph);      graphtraversalsource g = graph.traversal();      system.out.println(g);      vertex fromnode = g.v().has("nodeid", 0).next();      system.out.println("node calculating child nodes : " + fromnode.property("nodeid"));      long st = system.currenttimemillis();      system.out.println(g.v(fromnode).repeat(out("childs").dedup()).emit().count().next());      system.out.println("time : " + (system.currenttimemillis() - st) + " milliseconds");      graph.close();     system.exit(0);` 

it takes 41 minutes parameters change or add in decrease in read time occurs in time

thank once again , sincerely hope solve problem...!
