I know 4 bytes isn't alot, but i'm consider maximum cost saving of bandwidth.... the alternative way is to use time as the indicator

That doesn't make a lot of sense. All the time you spend waiting is equally wasted badwidth. Use or lose it.

If you're thinking about the cost of those extra 4-bytes, you said the file sizes are 10.5k, which means those 4 bytes represent 0.009% of your traffic. How much can that be?
