CentOS - Feb 2008 - Centos Guys: Any estimate of recent torrent savings?

Just wondering if the community has any stats available from the tracker
showing savings from torrent (up|down)loads. I'm seeing *lots* of
activity on the live CD. Between that and the two CentOS releases I'm
sharing (4 DVD & 1-4, 5 DVD & 1-6) my current session has sent out about
20.3GB.

Since I started using it regularly, I think I've sent >= 0.4TB.

If some really good numbers were available, it might encourage others
when they realize that all this translates to faster syncing of mirrors,
faster initial release downloads, reduced costs to the project, etc.

I recently increased my cable modem speeds (U.S. $10/mo seemed worth it
to me even though I don't get the benefits of the added download speed
often - nature of what I do and all that) so I could upload appx. 60KB/s
instead of the previous appx. 45KB/s. And the new {lib, r}torrent from
rpmforge has DHT capability included, which I activated, and I think is
increasing the number of peers/clients with which I see exchanges. I
don't know how badly this might cause under-reporting of your stats.

Just curious, no big need.

Bill,

Our tracker shows downloads since it's last restart here:

http://torrent.centos.org:6969/

The vast majority of the total transfer amount is provided by Non-CentOS 
  sources.  That amount (as I write this e-mail) for the last 67 days is:

119.98TiB

Or, almost 2 TiB per day of bandwidth that is saved by the CentOS 
Project (that bandwidth is available for other things like mirror syncs 
or yum updates).

As an added benefit, for me at least, when I download via Bittorrent, 
after an initial delay of about 3-4 minutes to find peers, I always 
download at my full D/L pipe capability, no matter where I am.  If I get 
the ISO from a mirror, I am limited to their total d/l speed, usually 
for most that is significantly less than 10mbit.

Thanks,
Johnny Hughes
