title: Is player prefs saving values slow?
body: <p>I found some answers about this but they vary from age to age (last one 2015) so i was wondering about this because i need it so to know how to build my code. I have leveling system with experience and let's say player can get from 1 to 10-15 times xp in one sec (let's say he use AOE spell and kill 15 mobs) so i want to know what is better approach:</p>
  
  <ul>
  <li>Every time player gains XP it saves it directly with <code>PlayerPrefs.SetFloat()</code> so it can happen that it will activate <code>SetFloat</code> 15 times in one moment</li>
  <li>Load player xp inside code on game start, than to do all calculations inside code and at the game close i save that to PlayerPrefs.</li>
  </ul>
  
  <p>I would like to use first approach since for me it is much safer but i do not know if that would be slow.</p>
