title: Hibernate: load vs get
body: <p>I know that this is a common question that was described a lot of times.
  But still I can't get some thing - what about performance? Which method is faster?</p>
  
  <p>Actually, I need a simple thing: the page makes a POST-request: id=0, name='John'. The server-side script should check if id=0, then create a new record in DB, otherwise update existing.</p>
  
  <p>I think that get() is more usefull for me because it will return a NULL in case of record is not exists in DB, while load() can return some temproray object.. Am I right?
  Thank you</p>
