title: Rest vs. Soap. Has REST a better performance?
body: <p>I read some questions already posted here regarding Soap and Rest
  and I didn't find the answer I am looking for.
  We have a system which has been built using Soap web services.
  The system is not very performant and it is under discussion
  to replace all Soap web services for REST web services.
  Somebody has argued that Rest has a better performance.
  I don't know if this is true. (This was my first question)
  Assuming that this is true, is there any disadvantage using 
  REST instead of Soap? (Are we loosing something?)</p>
  
  <p>Thanks in advance.</p>
