  Check out the latest SVN version. Jörn and Mark put some time into optimizing performance. If you use the "blank" module you have Lobos suggested "hello world" module
  
  As far as I understood Jörn, there's no unnecessary SQL call for such a basic call.

  Lobos

  Just wondering - if I create a module that simply outputs "hello world" and exit(); will there be routines run from the core that are not required to acheive this? ie render stuff (Smarty, theme), database stuff (adobe), etc, etc. Is postnuke set up to only run what is required at the time?

  
  
  I have just performed a performance review of a stripped down .8 SVN checkout - with no visible blocks and a "hello world" module as you suggest. As a result of this I was able to locate a few places where we could improve performance (which has been done and in SVN). So, as far as I'm able to debug and read the profiler output, there's no unnecessary overhead involved in displaying a simple page.
  
  Mark has in addition to this implemented a singleton pattern for the pnRender/Smarty stuff. This has removed a lot of the performance issues from pnRender.
  
  So, at the time of writing, we are not aware of any easy-to-spot bottlenecks in the core.

  I have installed a test-site with the 25. June .8 snapshot together with a customized Pagesetter database to test pnRender and theme caching. pnRender caching works well, and theme caching has improved a lot - but with the following defect: manual entries in Pagesetter filter forms are cached, too. So once you have filtered for something, this filter and its results will always be returned and overwrite any new manual filter entry. Using [nocache] for the whole template did not resolve the issue. The same is true for check boxes in the core setup, e.g. after checking the theme-cache-checkbox you cannot uncheck it anymore. Only manual removing all cache-files from the server enabled me to uncheck it again.

  Comparing with a friend the PN0.8 SVN20071007 (almost RC2) with Joomla 1.5 RC3, here are the Benchmarks results.
  
  Important Note:
  This is over a desktop PC, nothing compared with a server hardware capabilities. Just Ubuntu 7.04 with xampp 1.6.4 (Apache/2.2.6 PHP/5.2.4)
  
  
  PostNuke 0.8
  pnRender & Theme cache enabled, template check disabled.
  Not using sessions for unregistereds.

  Clean installations,
  Andreas08 PN theme vs default Joomla theme,
  PN: Who's online, Main Menu, Login block. Two News articles.
  Joomla: Who's online, Main Menu, Login Form, Two News articles (mods, components, whatever!) all the rest disabled!
  
  
  Obviously, i'm not a Joomla fan but my friend yes, and the results with the phisical order of PN, and the cache results, give him some reasons to think that PN is better.
  Just to think a little, i'm happy with the pnRender performance, and with the cache design off course, i know that can be improved in a further, because with cache and without PN cache, the difference is minus than 100 request per second...
