Performance issues

Tuesday 10 May 2005 5:11:37 am

I experience structural and critical down-performance: admin interface experiences 30 sec. time out on every action I try to perform. System is functioning since once in about 20 page reloads the requested page is displayed. This results in an unworkable situation and drives me to the conclusion to call the whole ezP-thing off :-(

Please do provide some suggestions to diagnose the problem and resolve this issue.

Thanks for the reply.

Unfortunately I can't give much more information since this is a hosted environment. I don't know the specs of the hardware, although I know it is shared quite extensively. At least the database is, since during installation of ezP I can choose from a pretty long list (around 30) of installed databases (naturally only one is available to me). Anyway, I presume the hardware specs may be marginal but reasonably sufficient.

Apart then from the hardware spec, do you observe any configuration aspects that can be considered "too limited" or out of normal operating envelope or contradictory? For instance, why is ezP indicating the absence of PHP accelerators whilst phpinfo() claims the presence of Zend optimizer?

Thansk in advance
