thank you for your prompt answer.
Your tip is already implemented
I have published this site at http://www.tucantucan.com and responce time is about 30 sec for main page, that is completle unacceptable for me.
I do have made several tests on local network to estimate my responce times. Even Pentium-100 was performing all tasks at blazing speed. At this point I am unable to answer is that site is CPU intensive or is it hosted on overloaded PHP+MySQL server.
I expect to have 300 visitors per day, with avarage 50-100 MySQL queries per visitor.
Jeff, I would very appreciate if you visit mentioned site to have an idea what I am up to. It would be my pleasure to provide any additional information.
