Notes from a man with a few terrabytes to his credit:
The progress in azureus or Utorrent (isn't it actually MU torrent? the U actually being a greek mu, no?) is, I fear, non linear. In other words it may grab a little bit from the start, then the next bit you get is from half way through,then a bit from somewhere else, etc etc. You can (in azureus at least) prioritise the first and last sections to enable you to preview the download (.avi files have their time index at the end and wont play right (or often at all) without it).
With regards to tuning for download speed.....set your upload to about 20k to start with, then basically tweak it until you find the point where it doesn't choke the inbound (when someone sends you a bit of data, they wait to hear your machine say "yup, got it", if your outbound connection is too busy, this receipt is delayed, so the other end waits before sending you any more). If Utorrent has a stats page, you basically want to set your outbound limit to the highest value (or a k or two less), that still gives a flat trace on the outgoing graph....if it starts jumping up and down, it's choking.
Of course the above assumes a quite active torrent, where the capacity is available to give your connection something to think about. On a torrent with low numbers of peers, you're in the lap of the fairies, but although it is hard to use such a torrent for tuning, it'll feel the benefits if you've already sorted things.
One other note re: azureus....do NOT set the incomming limiter to anything other than the "dead 8" (
), I've discovered that the only thing it limits is the speed stuff is written to disc......in other words, if you have something running at 200KBps, and you throttle it in azurues to say 20KBps, it will actually still download at 200, but only write 20 a sec into the actual file, if you then lift the limiter again, it syncs it all up again. This is odd enough when you have 1 or 4 GB of RAM, where it can buffer till it's tits turn blue, but if you only have 128MB, Terrible Things will happen quite quickly.
BTW.....
And as long as you do not download "another pathetic pile of shite for illiterate, inbread, seppo spastics", or $POPTARD's new album, the various organisations dedicated to making the whole world obey US "law", will leave you alone.....the do not care that I have downloaded the soundtrack to Joe 90, or the old William Woollard series "secret war".
BUT, for extra safety, if your torrent proggy offeres it, switch on "safe peer". It collects a list of known pig filth and Govt IP addresses, and if any of those try to open a connection to you, they are told "fuck right off foreign cop!". Most handy.
