Been going on for about a week now. Spoke to first round comcast support and she said she wasn't allowed to comment on Comcast's policy toward file sharing. This is pretty clearly purposeful slowdown of ALL network traffic at the modem itself when sharing is activated. Or am I just missing something here? Workaround...through a proxy? Recourse with the company? Anyone else seeing this? You have too many connections active and/or you are saturating the upstream. Lower the number of connections and set a limit on your max upstream. 20% of your upstream line speed normally does the trick but ymmv.
Fixed margin blowout. ~sorto' |

Yeah, you are missing something.
First, you are not tracing to your cable modem. It looks like you may be tracing to you WAN default gateway...
Second, what did you expect ? Of course your response time is going to rise if you are saturating your upstream.
The only way to confirm that Comcast is throttling your connection is to do a packet dump and check for RST packets. |

Try capping your upload to 80% of your true upload (not the PowerBoost upload, 80% of your 384kbps upload). It's not Comcast's BT filter, its their upload buffer that's screwing you.
Many cable companies do this. If you limit your U/L to less than your true upload then the buffer won't fill up, and as a result packets get through quicker. |
