title: What makes the Java compiler so fast?
body: <p>I was wondering about what makes the primary Java compiler (javac by sun) so fast at compilation?</p>
  
  <p>..as well as the C# .NET compiler from Microsoft.</p>
  
  <p>I am comparing them with C++ compilers (such as G++), so maybe my question should have been, what makes C++ compilers so slow :)</p>
