Hi Timothy,

Thanks for the bug report. I'm currently working on the bittornado
package with Micah, so I thought I'd try to help with this.

First off, if it's not too much trouble, could you give me some more
information on what you have discovered, and how you discovered it. You
say the cycle consumption is higher, but how high? What numbers are you
seeing for btdownloadgui.bittornado, btdownloadcurses and
btdownloadgui.bittorrent? Maybe also some details on your setup (CPU,
Memory, Xorg version)? If possible, could you test it on a public domain
torrent (perhaps from http://torrent.ibiblio.org/) that I can also test?

On my machine (AMD AthlonXP 2400, 512MB RAM, Xorg 6.9.0.dfsg.1-4) I have
found the following:

Viewing on remote screen through SSH forwarding:
 * btdownloadgui.bittornado: 5-6% (consistently)
 * btdownloadgui.bittorrent: 4-6% (~5% on average)
 * btdownloadcurses: ~3%

Viewing on local screen using fvwm window manager:
 * btdownloadgui.bittornado: 5-6% (Xorg: 1-2%)
 * btdownloadgui.bittorrent: 4-6% (Xorg: 0.5%)
 * btdownloadcurses: ~3%

I have noticed higher CPU usages with btdownloadheadless in the past,
but always when I was downloading something where I was connected to
hundreds of peers. I believe the CPU (and memory) usage will always
increase with large numbers of peers for all of the bittorrent based
programs, so when comparing programs it's important to use a torrent
with similar peer numbers.
