BT infinity upload speed

[fourstardan]

Hi,

I've had this issue for years now where when I upload a youtube video it absolutely drains my download speed.

Has anyone else had this problem?

Im on Infinity 2 and getting a decent 30 odd MB usually.

standard for an asymmetric connection
when you download using tcp you are sending ack packets in return, they are much smaller than the data packets, they can be up to an 80th the size, but that does mean for a 30 gigabit download you need to have available a good 400k of upload just to make it work, if you saturate your upload then your download suffers a lot.

I used to work getting my hands dirty with Infrastructure so the async part was what I thought it was.

Maybe videos on youtube have just got too darn big now based on size/quality and I am getting too old to realise.

Find out what your upload speed is and put a QOS limit on your router for half-3/4 of that. That should stop any one device from hogging the whole bandwidth.

As above, try putting a QoS limit on. Could also be bufferbloat making an impact. What does your home network look like? Could even be as simple as a switch stuck on half duplex.
