I've been wondering how much information can be sent in one http request? I've been reading that the less http request a website has the faster it loads. But what about tiny image compared to a larger image, does it take as long to request a tiny image as it does a larger image? How big can an image or file get before it takes two request to load it all?
It only takes one request to get each file no matter how big the file is so the overhead of requesting files is a fixed amount per file.
The other overhead in requesting the files is in finding the servers they are on which involves a domain lookup for each separate server that they are on (meaning that loading them all from the same server is faster).
It is the download times for each file that are affected by their size. So 100k of files takes approximately 30 seconds or so on a dial-up connection (by which time most visitors will have left so you needn't worry about sizes bigger than that)
The time to request each file is usually insignificant compared to the download times unless you have hundreds of files in the page.
That cleared it up for me. So like if your page is long (lengthwise) we could put better images on bottom because their (the customer) isn't going to get there before it loads?
Also, while I'm thinking of it. I was reading that some like Google somehow "loads" the images for the second page (in the background) while the viewer is still on the first page. Do you know where I can find out how to do that, as I forgot where I read it at?
