[opencms-dev] OpenCMS performance tuning

[Achim Westermann]

Hi, 

If I had to guess from this information I'd say: Relaunch the website (with a newer version of OpenCms). And not a relauch with a different design but all the old code still in action. However this is just a guess. 
>From the Software point of view I can say that this should not cause bad performance (except for Oracle).  
I'd try to find out the bottleneck parts of the web page / code and in an first attempt try to use flex cache tuning whenever possible. Regarding system design: Do avoid calls to remote systems if you can (speed, stability), try to keep all components (apache, appserver, database) on a single machine. And virtual machines.... well I had my issuses with team developement on vmware. 

HTH, 

Achim
