Speed Of My Web Site

Hello,

I did not which topic to choose

My question to You is: “how to make my web site, be faster on user side?”, it is an IP forwarded by for example dyndns.org, and pages are not downloaded so fast, I thought that a router has to be placed between modem and pc,

is it possible only with one xp, and a web server build a web site as fast as google.com for example?

thanks for your time
