I'm reaching a breaking point with Comcast and wanted to talk this thru....
I have a unix shell account on a server in Canada. My family and I use my shell account to transfer home movies back and forth (sftp, rsync over ssh).
This evening, like many other evenings in the past, I started downloading a video from the 4th of july. The files are multiple 2 gig files and the whole folder is 31 gigs in size (family is all 1080p crazy). I initiated the file transfer using rsync over ssh from my home storage server. I had gotten about 7 gigs downloaded at roughly 6.74MB/s when I realized that some of the files were duplicates. I stopped the transfer, logged into my remote server and removed those files. When I started the transfer again, it barely would touch 300 KB/s, so I canceled it out of frustration.
I then logged into my remote server and initiate a rsync over ssh back to my home server. My home server has ssh natted on a high uncommon port (not 22). Behold, I am now running at full speed again. Well I noticed again that I missed some duplicate files and canceled almost right away, removed the files from remote server and restarted again. This time I was back to running around 300 KB/s... again... WTF!?!?!
For testing purposes, I added additional NAT ports that forward to my home server (ssh). Then retried the rsync over ssh from the remote server to my home server on the new NAT ports and again... I am back at full speed...
This cat and mouse game is pissing me off and I believe that I am being throttled. But for the sake of enlightenment, what are your thoughts?
Here is a copy and paste of my modem signal levels (Surfboard 6121).

Some other useful information, I have the 50 meg blast package in Denver. During this, I have been monitoring my smokeping installation and I have not dropped any packets. Speedtest.net shows my bandwidth as being above the advertised 50 and I didn't check shaperprobe.
Thanks in advance =)
