BitTyrant V1.1 is a hot-rodded version of the popular Open Source BitTorrent client Azureus V2.5.
The modification is fiendishly clever. While most clients only consider the number of peers available for downloading, BitTyrant also considers the capacity of each peer and the data rate required to ensure reciprocation. It then utilizes this information using a dynamic algorithm to send only to the highest capacity peers data at the minimum rate for them to reciprocate.
In plain English this translates to your downloads running faster, much faster; around 65% on my tests.
Now, the standard Azureus client may be one of the most full featured clients available but it’s certainly not the fastest kid on the block. With the BitTyrant mods, though, it’s a speed demon. In fact, it’s the fastest client I’ve tried.
Here’s the downside:
First, this kind of mod breaks down some of the fairness characteristics of the BitTorrent protocol. If you are not comfortable with that then don’t use BitTyrant.
Second, the standard Azureus client is updated regularly but there is no guarantee that BitTyrant will be kept up-to-date with the latest version. The authors of Azureus may even knobble the product to prevent the mod.That said, the current V1.1 version of BitTyrant based on Azureus V2.5 is the fastest BitTorrent client yet.
