shaperprobe results far better than speedtests

A lot of test weren't designed to deal with current high speeds, which were unthought of at home just a few years ago.
Shaper probe being a university research project was planned around full internet and internet 2 speeds,
further it measures and display both the boosted rate as well as the shaped rate rather than the limited time sample averaging of the typical commercial test.

I find shaperprobe test results to be fairly consistent from one time to the next and from one day to the next, with minimal variation in the reported results.

I find the speedtest results to vary all over the place from one invocation to the next, even when the speedtests are done back to back. I have 16mbps download, so that's not too fast.

I've done a speedtest, followed immediately by a shaperprobe test, then repeated the two again. The shaperprobe test results were consistent, the speedtest results varied by nearly 40%.

I have no idea why the inconsistency in the speedtest results, especially in light of the wide usage of that test. I can only surmise that it might have something to do with relying on a Flash-based browser plugin for the testing engine.

Take note when checking for your advertised speeds. Never rely on speed tests. Trust 2 things:

1) Shaper Probe

2) Run your own speed tests by downloading several files from known fast servers. That will definitely max out even 105/20

Other then that, take whatever any other speed test or site tells you with a grain of salt.

Thanks for your responses. So these shaperprobe results are fairly convincing proof that I am getting close to 105 up and 20 down?

Downstream: No shaper detected.

Also I'm not sure how how to run my own speed tests by downloading several files from known fast servers. Could you give me an example of how to do that and how to determine the results?

Thank you all so much, really really helpful.

Thanks everyone, great forum.

You're very welcome. Also, you might want to think about registering for the site. It'll be easier to track replies and other things. It's free as well.

I hear ya...I guess mileage will vary. It's been good here and the readings have been pretty consistent. But I agree with the group that ShaperProbe gives "truer" results.

Hi All,
The last few times that I tried to perform a test using their software, I keep receiving the " All of our server's are busy' notice. And the only point of contact that shows on their site is this:

I don't know what I'm doing wrong , but I can't seem to get the e-mail address corrected so I can send a message. I know the 'at' should be replaced with '@' .

Hello,
Once again today I tried to perform this test, and once again I received the notice of " All servers are busy, please try again later ". Has anyone else been receiving the same notice ?
Thanks,
David

Hey Davy...I just tried it and it went through fine. Have you tried trashing the version you have and reloading it from the site and trying it again? Hope it works out for you.

So I take this is an attempt to throttle 94289 down to 55589 seeing I have the extreme 50..
