I had 50/15 and never went above 10 up. Changed to 105/20 and still never went above 10 up. I'm In Fort Pierce, FL south of you by 3 hours. I sent a message on Comcast Direct forum and was answered by ComcastSteve that the CMTS was set for 10 up at the present time and would not go higher till it was upgraded. So I live with the 10 up hoping that sometime in the future the CMTS will get upgraded.

I would recommend that you post in the Comcast Direct forum and ask if the CMTS your on can handle anything higher before going crazy like I did. Just to let you know sometimes there busy and do not answer for a few days.

Thank you for your replies.

As far as the CMTS, I will take your advice and post on the Comcast Forum. Be interesting what they have to say. I will post back with response.

For all you network guru's, my power and SNR levels are ok? Anything I should improve on?

Why is it running at IPv4?

Where did you verify what the current speed is? Unless your in or near areas in competition with FIOS the speed would be provisioned at 50/15 instead of 50/10, which is what sounds to be the case here

When upgrading my service tier from performance 20/4, the comcast rep told me the speed for extreme 50 is 50/15.

Thank you,
Monnie

I may be missing something here but your ShaperProbe upload measurement seems way off. It is showing only 1,232 kbps? That is only a little over 1 Mbps...nowhere near 10 Mbps.

On my Comcast 27/7 Business Class service my ShaperProbe upload is 7,914 kbps.

Why would your ShaperProbe result look so much slower?

I was seeing the same thing. This leads me to believe that maybe it is a modem configuration issue (wrong config file sent to your modem), or as GSTEXEC1 See Profile has said, your local CMTS not being upgraded yet to support that speed plan.

For reference, I ran a ShaperProbe test just now. My results are below. By the way, my plan is "Performance w/powerboost", which in my area is 25/4.

ShaperProbe is not accurate by any means.

People say use it and what not but like any other service it all depends on the hosting server and which server you connect to.

ShaperProbe has a list of IPs and sometimes mine connects to a slow one and sometimes a fast one.

It takes a few runs across different IPs to know an decent avg. He probably just ran it once.

Looks like Performance is 16/2 sustained with Powerboost bursts to 25/4 in your area.

Obviously it can vary. But the variance, in my experience, has been very minimal.

Maybe I'm not alone with ShaperProbe reporting inaccurately. ShaperProbe has been borked for me for months.

Interesting. Have you compared traceroutes to the server IPs where you get funky results? Or do you get low results every time?

I get low results all the time. I can download/upload large files and see correct transfer rates for my provisioning. I have not figured out why ShaperProbe is inaccurate for me now.

Hmm, weird. Have you emailed Partha about it? Very responsive in my queries and very knowledgeable. If you care to figure it out of course. I would hate it if I couldn't rely on one of the only speed tests runnable on non-windows/mac computers.

I also get occasional bad/irrational SP results.
I know one of the east coast IP's does poorly to me so when I run SP I run it 3-4 times in a row (the selected server rotates) and guesstimate the average, while tossing anything that look bad.
Not exactly science, but tests are a snapshot anyway, and the only speed that really matters is ACTUAL transfers.
BTW it's under Win7-64 using the new code version that is inconsistent, XP and vista machines seem fine

I've been lax with looking into it further. I should investigate since there may be others who may be seeing this. Might be worthy for the benefit of others.

I think that these are isolated cases and more so the exception and not the rule. IMHO, it is still a gold standard measuring tool and I will still be recommending its use when I want a more accurate reference than any of the run of the mill Flash and Java based speed testing sites.

You would think these speed test sites would come up with a way to measure the same kind of thing, then display the peak (powerboost) speeds as well as the sustained speeds.

But as we know, it would take more time and more bandwidth on the part of the servers hosting the speed tests, so that's probably a deterrent. But given many cable providers have implemented powerboost, I'm surprised there are no good web-based speed tests sites that will break it down like shaperprobe does!

I agree. I've not looked into because it works for the majority. I just use other resources.

If you know of a web-based test that can detect and report PB and also sustained speeds, please share!

Ah ok, so these are just large files to download? I have a couple of mirrors I use to do that, but this is a nice link, thanks.

I was thinking of something more like shaperprobe, where there's a flash/html5/java UI and it runs a longer test or uses udp as shaperprobe does to give an idea of PB and post-PB speeds.

I wish there was a ShaperProbe equivalent. I haven't found another. I just check with large file samples.

FWIW, I get download speeds that are off by 30 Mbps with the largest DL file there. Guess that that server does not open up multiple concurrent sockets / streams to really reveal the true capability of the pipe ?

For speed tests with large file downloads/uploads, I use the TestMy.net site: »testmy.net/

To get past the PowerBoost effects, you can custom select test file sizes of up to 200MB on the downstream, and up to 33 MB on the upstream.

That one seems to top out around 20Mbps for me at home (but I'll try it at some other locations)
»www.linode.com/speedtest/ works great if you open multiple saves, either the same server or around the world (which mimics real web pages and/or P2P sources) I consistently hit 37.50Mbps on Blast! during the boost phase here.

I've had that one bookmarked for a while. It's good as you say, but I don't use it. I just like simple down & dirty tests.

Yeah, you've told me that before, but it seems to work pretty good for me. For my Performance 16/2 connection, it just gave me a result of 14.8/2.5 (with 100MB/25MB test files).

But to each their own, I guess.
