Depends on how popular it is. How many people have the file, how many of those you can connect to, how much upload bandwidth they have left over, etc. You cannot always expect high speeds. Especially if you are downloading from one or more dial up users.

Do the occasional repeat search, use the Find more Results option.

Oh, I often browse hosts with similar files, that can potentially take me outside of my normal search horizon finding new hosts.

I find often my uploads are much faster than my downloads. Perhaps because I normally seek harder to find material. My potential download speed is between 5-11 times that of my upload capacity.
