Washington, DCBelow & attached are the test results I'm getting on my Comcast Blast service in the Washington, DC area. Are the results consistent with the newly announced Blast speeds?
DiffProbe release. January 2012. Shaper Detection Module.
Connected to server 38.106.70.175.
Estimating capacity: Upstream: 6769 Kbps. Downstream: 30733 Kbps.
The measurement will last for about 2.5 minutes. Please wait.
Checking for traffic shapers:
Upstream: No shaper detected. Median received rate: 6608 Kbps.
Downstream: No shaper detected. Median received rate: 30128 Kbps.

North York, ONI just re-ran the speed test using » speedtest.comcast.net/and got a download/upload result of 59 Mbps/10.39Mbps. The results from the comcast site are consistently better then other test results. Are they biased? can they be believed? |

Re: [Speed] Northeast speed changes coming.It seems like most people here agree that Shaper Probe is more accurate to measure speed than any of the speed test sites » www.cc.gatech.edu/~parth ··· obe.html |

The results from the comcast site are consistently better then other test results. Are they biased? can they be believed? I believe that when a Comcast customer uses the Comcast/Xfinity speedtest site, the servers they can select are all Comcast ones, so the data transfers stay within Comcast's network and don't experience any slowdowns that occur when interconnecting with servers in other ISP networks. If I select the same Comcast server on the similar » www.speedtest.net site, I get basically the same result, but if I select a server that is located much closer but which belongs to another ISP, the results I get are usually not as good. |

This raises an important issue: What is the purpose of a speedtest?
I use it for consistency. Am I getting a consistent speed over time. Therefore, I have no problem using the Comcast one.
For what am I really getting (no Speedboost Impact). Then I use ShaperProbe. |

I don't use speed tests for anything more than to verify that my connection is working as expected. It's simply a first step that I can take in troubleshooting before applying more exhaustive procedures. I could see in a few seconds that the recent upgrade was not in effect through a quick speed test. After resetting my modem/router, I could then verify that the speed increase was working, all through a simple online speed test. |

Your getting some pretty good download results. Your results can be deceiving because from test to test. But If you are consistently getting that speed from test to test, then you can confirm with speedtest.net which has more test sites. Of course I use shaperprobe and a number of other test sites. Also a lot of different conditions can produce different results even on the same machine not withstanding the conditions outside of the home. Example: Wireless N
Wireless G
