title: Performance increase using Smarty + Caching?
body: <p>I am going to start using codeigniter, but since it only offers to cache everything or nothing (which would not work, because I have logins, and other areas which cannot be cached) I was wondering whether it is a good idea to use Smarty.</p>
  
  <p>The only concern I have in this question is speed. (No yes/no smarty general question.)</p>
  
  <p><strong>My Question:</strong>
  CodeIgniter with some db queries (blog, loading data for pages from the database, etc.)</p>
  
  <p>vs.</p>
  
  <p>CodeIgniter + same db + smarty + partial caching (and of course if smarty->is_cached(.tpl) do not do any db requests)</p>
  
  <p>What is fast, what should I use. Are there any smarty-benchmarks I did not see? Starting at how many db request, would you say, smarty improves performance noticeable considering you have to also load the smarty library?</p>
  
  <p>Thanks in advance.</p>
