Thank you friends, I was not expecting so many replies to this question. Still I am not sure if I’ll get the results. If I become successful then I will post here my results and details other details. The client is non-technical and doesn’t know that this is waste of time but he pays me small amount for services I provide him.
Thank you catacaustic for your reply.
Actually one of my client is curious about how many people wait until his site fully loads in browser even if it runs very slow. This website is about automobile showroom. I don’t know why he is curious about this. Perhaps it’s a kind of survey.
