What's wrong with Apache + php + mysql on Windows?

Hello, I can't understand the reason apache server running locally on my Win98 machine delays so much to respond browser when accesing php scripts in the form http://localhost/myscript.php When I transfer php scripts to host server via FTP, script execution is immediate, even remote server being in another continent. I was running apache + php + mysql on Win95 and delay was terrible. Now I moved to Win98 and delay became still worse. I know some parameter in httpd.conf or php.ini should be changed, but how to kwow which parameter?. Thanks for any idea. Mig
