  Hi
  
  The Xanthia caching system is totally broken under linux.
  
  I installed postnuke RC1 full package (normal install with
  mysql and basic modules installed), logging in, going to
  layout and activating the xanthia module caching in the xanthia
  settings.
  
  The result is shown here: http://88.198.46.59/
  
  It looks like block problem, but thats no true - caching blocks is DISABLED
  on that installation.
  
  I did another test installation on a 2nd linux server with different PHP - same
  result.
  
  My test & work installation under windows worked fine.
  
  Here are the 2 servers. The 88.198.46.59 one is a 2GB Hetzner AMD64 with
  Debain Etch and modified LAMP system with latest settings. php5, suhosin,
  eaccelerator, adodb, mod_security - you can check it here:
  I disabled for testing purpose the eaccelerator on this server.
  
  Site: http://88.198.46.59
  PHP info: http://88.198.46.59/info.php
  
  
  The 2nd one is server4you vserver, debian etch with php4 and eaccelerator
  enabled. Pretty much a different system. Same problem.
  
  http://web2.168180.vserver.de
  http://web2.168180.vserver.de/info.php
  
  On the first one i disabled the PnRender caching AND checked the block module in the
  xanthia caching - on the 2nd one is all enabled. I cleared for both server all
  pnrender & xanthia caching directories by hand.
  
  So, its not a side effect... If a dev needs access to the systems, please PM me.
  Both server will be full reseted with new image after this, so its no problem.

  I forgot - Its NOT a visualation problem - the blocks are not the problem, you
  will get wild effects for example in the admins menu with your auth key - which
  makes changes nearly impossible including reseting the xanthia caching. Be careful
  when you test it on a system where you don't have full access.

  Please be careful with such absolute expressions.
  
  Re-check with one of the default themes supplied with the RC1 and tell us which theme you are using. A first wild guess would be a broken selfmade theme.

  There is definately a problem - but only with themes that supply thier own block templates. It seems that the block output gets cached when it shouldn't. And since the block template doesn't have a suitable cache id then you see the first cached block repeated everywhere.

  I've now fixed this problem, at least from my own limited testing, in SVN. Please check with the next daily.

  Will checkout the SVN tomorrow and isntall it on the server again.
  
  Is there any special SVN tag/branch i have to checkout?
  
  EDIT: *Ah, only saw the SVN... Had to much SVN checkout the last days. Will use nightly.*
  
  As i described - its the standard debian LAMP server in 2 versions
  where i loaded PN on - no changes, standard setup. Checking with
  the standard templates of the package only.
  
  After finish the installation i go direct to login, admins, select template and
  activate Xanthia.
  
  It must be problem with linux because it works fine for me under windows.
  Well, nearly - because under normal windows, localhost the performance of
  the Apache is pretty bad. Not a good way to test caching for me.

  If testing is needed: The first server is new without any content, i have to prepare and test there the
  website so or so. There is nothing personal data stored, so i can grant there ssh login for a PN dev.
  Just PM me here please.
  
  I will request a new OS image after this from the provider because i test the hardware & setting alot,
  its really no problem.

  Just tested the changed pnTheme.class.php file - its works like a charm.
  
  http://88.198.46.59
  
  The cache time is 10 seconds, you can see good when the cache is triggered
  by the page render time on the bottom.
  
  Just because i had the php.ini opened:
  
  On that server, the postnuke site with some modules enabled
  without eaccelerator caching
  
  like 250ms to 340ms for a initial page
  and constant 0.07sec when caching
  
  With eaccelerator the render time dropped
  to 0.09sec to 0.11sec for a initial page (every 10 or 20 pages more)
  and pretty nice 0.01sec to 0.02sec when caching
  
  Pretty nice.

  Using a PHP Accelerator with any PHP program should see a 1-10x speed increase (for example with Gallery2 I saw a massive performance improvement on a site getting 500,000 hits a day). If you have the means, it's always a good idea.

  i'd suggest to try the 'Alternative PHP Cache' pecl:apc instead of eaccelerator (apc will be part of php6 anyway )
