Re: Qantas domestic Lounges pathetic wifi
Sorry if this isn't completely on topic, but I thought I'd jump in and explain a bit on bit torrenting and the effect on connection quality on a network.
Bit torrenting causes a secondary issue that most people don't know about. It is possible for only few computers running bit torrent software on a network to slow it down to crawl, even if they are only asking for 20% of the available bandwidth.
How? Bit torrenting works on the principle of downloading the one file from hundreds of sources at the same time. This means you can get your data fast, but you are also making many times more individual packet requests of your equipment than normal downloading. This isn't a problem if you have high quality switching infrastructure, but as it's a reasonably new phenomenon, most consumer router/switch/modem combos just don't have the computing power to manage bit torrent loads well. So what ends up happening with a basic router is it's processor memory fills up completely with packet requests from the bit torrent client and slowly works its way through them. You're packet request to see the Australian Frequent Flyer site also makes the list, but it has to wait it's turn.
An analogy might be one person turning up to Coles with a truck and asking for 5000kg's of product versus 4000 people only wanting a total of 1000kg of product. It takes 20 times as long to look after all those individual shoppers, as they all need to be served and that is time overhead, even though they only want 20% of the amount of product.
If you have a home router and do bit torrenting, you may have experienced this already. You have a bit torrent going and try to surf the web, but connection speed is rubish. You might blame your connection and reset the router, which results in a few minutes of improved connection speed. You are only seeing relief because the bit torrent client hasn't filled up the router with packet requests yet. Ten minutes later the speed slows down again as the packet requests rack up again.
What does this all mean? Either Qantas and other carriers lounges need to get some more expensive switching equipment, or we all need to be mindful of our fellow lounge users and save the bit torrenting for home. If you are going to use bit torrent software in the lounge, perhaps go into your bit torrent client configuration and configure it to only make a small amount of requests at any one time.
