Answer 1

Read the documentation first on how to achive the best performance!

Few tips:

-> Do NOT instantiate ODocument always:

  final ODocument doc;
  for (...) {
    doc.reset();
    doc.setClassName("Class");
    // Put data to fields
    doc.save();
  }

-> Do NOT rely on System.currentTimeMillis() - use perf4j or similar tool to measure times, because the first one measures global system times hence includes execution time of all other programs running on your system!
