Have you noticed?

Maybe it is just me but I have found that OH is SSSSOOOOOO slow to open windows or process a response to a post. I keep my cookies and temporary files cleaned out on my PC here at home and at work. So I know it is not just my home or work PC. I also defrag my hard drive on a regular basis. I switch to other websites real fast so I am thinking it is that it has to be the sheer volume of people that are on this website.

If anyone that is a 'puter guru out there that might have any other ideas I am open to them.
