Had a quick look on ye olde googlium and there seems to be a wealth of information!

Rather old, but rather good was this result from the first 10:

There is a host of things you can do, probably the best place to look is

This pretty much will cover everything you need to cap upload/download.
However you will probably be a lot more interested in prioritizing your
traffic. For example. You might of noticed that when you upload at your
full speed your download speed is severely hurt; this is due to the nature of
TCP (toasting of the return ACK packets). With QoS (Quality of Service, as
it is known in the trade) this no longer becomes a problem if properly
implemented and more importantly can be used to make sure your gaming traffic
and ssh/ping tools are unaffected even on a 'saturated' link in both
directions.

you might want to look at my QoS script if you cannot be bothered to learn
QoS, it is actually quite difficult, and is why CISCO charge a couple of
grand for a black box which does this all for you

happy reading
