The MT speed test is a multi-connection test, think 20 streams or =
connections at once. Most web based tests are single stream. Now you =
get into 802.11N speedtests where they are optimized for many =
connections MIMO operations, hence, a single connection don't show good =
results, where a MT test at 20 streams would. =20

Subject: Speedtest Results speedtest.net vs Mikrotik bandwidth test
All:
=20
I am having some speedtest results that are difficult to interpret.
=20
I am a small WISP multi-homed with Cogent and Level 3 in Houston, TX. I =
am running BGP with each with 100 Mbps+ on each link.
=20
Some of my customers have begun complaining that they are not getting =
the proper speeds. They are using speedtest.net and/or speakeasy.net to =
test the results.
=20
My network is Mikrotik based and as such, I have access to Mikrotik's =
built-in bandwidth testing.
=20
With a laptop on site, running against speedtest.net (which kicked me =
over to the Comcast speedtest server instance) I can only get 4 Mbps up =
and 1.5 Mbps down. That is consistent on their desktops too. We =
eliminated their routing equipment and other consumers of the bandwidth =
and tested and got similar results.
=20
But when we run the Mikrotik bandwidth tests (even to off-net Mikrotik =
devices in Hawaii and Mission, TX) we get 25+ Mbps synchronous.
=20
We have run traceroutes to various traceroute servers and they go =
through Cogent and/or Level 3. For the most part it does not seem to =
matter which path it takes, the bandwidth seems to be about the same =
going both routes.
=20
When we run the laptop-based btest.exe against Mikrotik bandwidth test =
servers, the laptop got significantly better results (14 Mbps) , but not =
25+ Mbps.
=20
It is almost like there is a Java based problem with speedtest.net.
=20
Thoughts?

Thanks,
