title: Performance in USING PERIODIC COMMIT n - Neo4j
body: <p>I'm using the <code>LOAD CSV</code> command to import nodes and relationships in Neo4j. For better performance I'm using as well <code>USING PERIODIC COMMIT</code>, because I use large files to import (+/- 50 millions of records in each file). </p>
  
  <p>I want to know if is better use <code>USING PERIODIC COMMIT 1000</code> or <code>USING PERIODIC COMMIT 5000</code> or a bigger number of records used in a bulk for performance.</p>
  
  <p>The fatest way is put a big number or the oposite? </p>
  
  <p>Ps: I have a lot of free RAM memory in the machine.</p>
  
  <p>Thanks</p>
