Re: [Speed] Comcast Business Class Speed Upgraded in California ropeguru  - since you said you're not seeing the erratic speeds after PB ends, would you mind collecting some data? There is a wireshark version for windows if you're not on a mac/linux/bsd box. Would you mind generating a pcap trace as I've done so I can look at it?
I can help you find a local mirror so we're comparing apples to apples for the test.

I'd be happy to as well (via linux) for 15/3 speeds
Edit: just tell me what to do to recreate your scenario

I'd be happy to as well (via linux) for 15/3 speeds Edit: just tell me what to do to recreate your scenario Thanks appreciate it! I've been doing the following:
as root: tcpdump -i em0 -w speed.pcap host 204.152.184.73
as user: wget »ftp://freebsd.isc.org/pub/FreeBSD/ISO-···vefs.iso
Then I open up speed.pcap in wireshark, then click the Statistics menu and then IO graph (thanks espaeth for the info on IO graph, it's much better than the tcp throughput graph).
From there, to get those 3 10s groups of images, I set:
X axis tick interval: 0.01s
X axis pixels per tick: 1
Y axis units: Bytes/tick
Then you can scroll left/right to see a zoomed in view of the traffic. In my cast right around 23.5 seconds in, speeds fall off then go into their sawtooth pattern. Your duration of PB may vary of course 
Thanks for doing this!

I will do it for you on Saturday. My computer has been taken over by the zombie wife hand braking Halloween movies. |

ComcastDJ -THAT is what the graph should look like. Please get the 27/7 plan fixed.

windows io graph |
I see the same erratic speeds (see attached), but what was interesting is that I did NOT see power boost from the windows laptop. Very strange...
