Paul Brandt	Thursday 12 May 2005 10:53:47 am 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 Best regards Paul Brandt

Great Post,

I gotta tell you ...Very Informative; props!

I only wish others would be so tenacious with details when they post to the forums :P

But you left out much information on the server's hardware (disk, amount of ram, idea of other users / sites / applications running on the server, <b>amount of memory allocated to php in the /etc/php.ini</b>, etc).

cheer up, you can do it!
