DSL SPEED |
|
|
I have a ADSL modem rated at 1.5mps
A test from an internet site computed the DSL speed .
798 kbps download
310 kbps upload
Quality of service 79%
Is the above good service ?
Should the download be about 1.5mps
What should I expect from the upgrade to 3.0 MPS |

I've never had DSL service, but that sounds decent (1.1 of 1.5)
since it probably doesn't include the overhead for headers etc.

That's way too low. I have ADSL service from Verizon which is advertised
as 1.5/384 and syncs at 1792/448k bps (which is known as over
provisioning) and receive 1525k bps downloads/370k bps uploads.
Most other DSL providers do NOT over provision, so if you're getting
80-85% or more of your package speed, you're doing good. The overhead is
about 15%.
Now to the core of the issue: web based tests are often quite
inaccurate. Where are you located geographically? If you're going to
rely on a web test, make sure it's close to you geographically. Better
yet, download a file via FTP from any fast public server - Here are a
few that give me steady topped out speeds and are load balanced [I'm in
NY btw]:
ftp://ftp.ea.com/pub/easports/demos/madden2004/Madden2004_Demo.exe
ftp://ftp.aol.com/aol6.0/171340/setupaol60.exe
ftp://ftp1.optonline.net/test64
Also if you're going to be using web based tests, use the DSLReports
JAVA tests at the nearest Speakeasy POP:
sfo.speakeasy.net San Francisco
lax.speakeasy.net Los Angeles
dfw.speakeasy.net Dallas
sea.speakeasy.net Seattle
nyc.speakeasy.net New York
blt.speakeasy.net Baltimore
You'll find many more here: http://www.dslreports.com/stest?more=1 (just
remember, JAVA tests are no where near accurate as distance plays a huge
role and so are overloaded test servers.)
People who have 3.0/768 are reporting ~2800k bps downstream and ~720k
bps upstream on Verizon ADSL.
If your modem has difficulty maintaining sync at 1.5 or have borderline
signal qualities, 3.0 is more demanding (clean line, good snr) and may
push your modem to loose sync. You can't know until you try. :)
HTH
Don't trust Web Based Tests is the point of this post.
FWIW on this cable connection, web tests rate it anywhere from 1m bit to
java tests at 8m bps or so. Here's it's true speed:
% docsdiag -v | grep -i "qos"
QoS max upstream bandwidth = 1000000 bps
QoS max downstream bandwidth = 10000000 bps
% wget ftp://ftp.ea.com/pub/easports/demos/madden2004/Madden2004_Demo.exe

If you upgrade to 3.0, you will get:
~798 kbps download
~310 kbps upload
if you test from the same testing site under the same conditions.
You should run speed tests from several locations, and the FASTEST speed
test is closest to your actual service speed. That's because speed tests
depend on the speed test server and the Internet, as well as your local
connection to it. So your speed test results are only going to be as fast
as (your connection, or the speed test server, or the connections between
then, which ever is slowest)
But assuming that you ran several speed tests, and the best download speed
you got was 798kbps, then you could conclude that your particular ADSL
connection is not as fast as it theoretically COULD be, due to local line
conditions and/or distance from CO. Therefore, upgrading to 3.0 would not
gain you anything.
Find your state, or a nearby state, on the following list. Run several
tests. If the fastest result you get is over 1500kbps, then you might want
to consider upgrading to 3.0. If you never even HIT 1500kbps running tests
from several servers in your state or nearby, then your connection is
already as fast as it's going to be. -Dave
