The original "mainline" bittorrent client was also written in python.
Also, I don't think BitTornado is as known for being memory and CPU
intensive as something like Azureus, though I'm sure it uses more than
something like libtorrent.

FWIW, being an interpreted language is not necessarily the major cause
of the problem. The torrents that DebTorrent has to work with are
quite large due to the number of files in them (probably an order of
magnitude larger than normal .torrent files). These are currently
stored in memory, though I am looking into alternatives. I'm sure
there are plenty of places where optimizations could be made in the
code to save on memory, but due to it being so young still I haven't
had a chance to get to it. There's also a bug in python 2.4 that
causes increased memory usage, which will be reduced when python 2.5
becomes standard.

Thanks,
