title: Tips on speeding up Drupal site
body: <p>We just implemented a drupal site.  Performance of the site seems to be an issue.
  We enabled drupal caching,  set up apache caching derivates.
  Repeated page visits are fast enough (coz  CSS and JS are cached), but initial page visits are still a problem.</p>
  
  <p>Drupal experts, could you offer us some pointers, on different techniques used to speed up drupal sites. (like DOs and DONOTs).
  Are there any other low hanging fruits?</p>
  
  <p>(BTW, DB is not a problem here. That layer is fast enough. Problem seems to be in PHP/Drupal layer)</p>
