While I had a long love affair with BitComet as my prefered BitTorrent client, it happens that I currently prefer to use the lean and clean uTorrent software. It is a bit smaller (but it has a tendency to eat up memory if left serving files for a long time -it’s ok if you stick to downloading) and it has a nice little interface that is clean and easily understandable.

As with many a BitTorrent client, µTorrent or uTorrent tends to have a relatively complex configuration. Many options, some of them utterly cryptic, a lot of them with a possible impact on performance. After months of tweaking, I think that I have obtained a configuration that is clearly optimized to download several giga-byte-sized packages (videos/movies, Linux distributions, full databases, etc.) on a fast ADSL connection (20Mbit/s, here).

So I was suggested to share it with all the ones who want to try and get quickly a BitTorrent connection working as fast as possible.

All the options

I don’t need to explain the choice of language (µTorrent has one great advantage of having such a large choice for localization).

I did not install IPv6 support (my ISP does not support it), but it is a very critical item to check because -as soon as it becomes readily available- it will bring a significant layer of compression and obfuscation to avoid your ISP throttling down your P2P traffic (as some US and Canada ISPs currently do; Shame on them!).

I don’t care receiving the beta upgrades (I’m all for the stability of software) and I favor browsing as anonymously as reasonably possible.

Since I am working at home, there is no need for the anti-boss key.

Download: I prefer to immediately pre-allocate file size (rather than seeing the software program stop later because it has been eating up all disk space), and I don’t want to the PC to shut itslef down while downloading. While it is generally good to reduce electricity consumption, stopping in mid-transfer is not good for the efficiency of the whole process.

If you want to do discreet (if not completely anonymous) P2P, Bittorrent and Gnutella or Kazaa are not your friends. With the advent of more attention from authorities, it is difficult to consider them as good opportunities.

I have been looking quickly at some of the possible solutions to protect your privacy while exchanging files over the Internet. I found the following ideas:

• Omemo is a recent Spanish development. I tried it and it is very obvious that the program is still in beta. Essentially, I was unable to download a file if it was not very small in size or to upload any. Let’s wait until it works.
• GigaTribe seems a good solution if you are willing to pay for the Premium package. It builds a closed network with your friends, but the standard (free) software is not able to grab files from multiple computers at the same time. So performance is very limited for the free version. GigaTribe3 is said to correct a number of issues some time later in 2008.
• Freenet is rather difficult to use at first, but if you run Thaw, one of the applications provided at installation, you will get a large choice of file downloads and performance while limited is not ridiculous: A few days for 2GB of video, it could be much worse. However, some may be troubled by the kind of data found there: While the common P2P data can be observed, you will also find conspiracy-related information and a quite significant load of pornography and child pornography (normally not found on the more open Internet).

I don’t know where the future of P2P lies, but it is certainly around some of these darknets (networks that are protected from external Peeping Toms). Freenet is supposed to be the best and most secured one, even if it is not perfect (it seems clear that some powerful agencies have setup some Freenet nodes in order to be able to spy the traffic).
