title: fastest technique to read a file into memory?
body: <p>Is there a generally-accepted fastest technique which is used to read a file into memory in c++?</p>
  
  <p>I will only be reading the file.</p>
  
  <p>I have seen boost have an implementation and I have seen a couple other implementations on here but I would like to know what is considered the fastest?</p>
  
  <p>Thank you in advance</p>
  
  <p>In case it matters, I am considering files up to 1GB and this is for windows.</p>
