Okay lets break this apart because it's a lot to answer all at once.
The topic says "site bandwidth problems" but whose bandwidth are you testing, yours or ours? What tests have you used specifically?
This has nothing to do with our bandwidth but everything to do with your resources. When you view a page with images and text like our front page your browser uses memory and processor resources to display it. As you allocate machine resources to do one thing it stands to reason it has less resources to do others.
The front page itself has no flash running but if it did it's still part of the equation where the flash would be using more resources on your machine. This doesn't relate to our bandwidth.
By tests do you mean what you've related here?
There's nothing running in the background costing us more to run the site than is necessary. Nothing here can compare to the terabytes of transfer we provide to facilitate the file downloads, that's our main expense.
That's what Google made their name with I would hope their searching is fast.
Our bandwidth and your bandwidth are two different things.
