title: SQL Server 2008 R2 Express limitations CPU, nr databases, max RAM?
body: <p>This Thread is quite interesting:
  <a href="https://stackoverflow.com/questions/1169634/limitations-of-sql-server-express">Limitations of SQL Server Express</a></p>
  
  <p>But I have further questions.

  <p>I have two questions:</p>
  
  <p>What means number of CPUs? Is it the sockets inside a server - for e.g. the server has two sockets with 4 cores on every socket - total 8 cores.</p>
  
  <p>Is SQL Server Express using one core or 4 cores?</p>
  
  <p>If I have several instances of SQL Server 2008 R2 Express on one machine. Is the 10GB limit a sum of all data of all instances?</p>
  
  <p>Best regards,</p>
