Is my page load time natural ?

Thanks for the reply.

No my theme is not heavy and i have few blocks enabled. also i have very few nodes and taxonomies. in some very light admin pages (like admin/settings/performance) it reduces to 350ms, but it's still so slow, and it means it can barely handle even 8 visitors at the same time even on my development machine which is actually like a non optimized dedicated server.

I already applied most of the suggestions in the the link you mentioned. but those optimizations are for after generating and sending the page to client not before that. my problem is the time php consumes for generating the page dynamically.
my site YSlow grade is 63.

Here (http://buytaert.net/drupal-webserver-configurations-compared) as you can see, dries mentioned that his test server with similar hardware performance to mine with lots of content and no optimization can handle i guess 3 authenticated users per second in front page. according to his benchmark , the drupal on my development machine should fly, the only thing i can think of is something wrong with either my server or my drupal installation. :( but the problem is i don't know what is that!

How much is your page generation time?

I really appreciate any kind of help :)

Hi, thanks for the reply
I enabled eaccelerator with the following configuration and page generation time is now 480 MS!! only 25% improvement!!. you said a bit high, does it mean that everyone have the same issue? because even 300MS on dedicated machine is hight (specially for a site with almost no content).
