 |
|
After bouncing around RoadRunner Nat'l Help Desk for almost
an hour, I finally got to speak with the California Tier 3 Help Desk
in Colorado(!).
After about 40 minutes of doing various tests and tracerts, and
a cute test at www.InternetFrog.com which measures percentage
of successful packets, it was determined that ROADRUNNER
has a problem in the CA.RR.com and probably SoCal.RR.com
regions, i.e previous Comcast and Adelphia regions.
Problem 1
The software that checks billing accounts to see what speeds
you're entitled to is scr**ed up so that the wrong parameters
are downloaded to your modem's bootup file. No matter how
many times the tech rep tries to correct your modem's parameters,
the billing account-checking software will override it and not
allow you to get the level of speed you're entitled to.
Problem 2
No matter how much speed you get as measured from TimeWarner's
speed website
(www.AccessTimeWarner.com/support/internet/speedtest/speed.asp),
a router upstream of the RR.com domain is apparently choked or is
malfuntioning so that less than 2 thirds of your packets get between
other websites and the RoadRunner network.. Thus speeds measured
from DSLreports.com or Reviews.CNet.com are much lower.
Both these problems are systemic and not a problem with your PC or
cable modem, and the Colorado Tier 3 techs have notified both the
Network Ops Center and the billing software departments about these
problems. But who knows how long it will to get them fixed. I'll wait
until January 1. After that, I'm off to DSLextreme if nothing improves.

I regularly get just under 5Mbps to my outside news service,
but your site says I'm only at 1.5Mbps.

What you measure is probably bps sent or received - NOT
what bits are received without a request to retransmit.
When packets are received with errors, a request is sent back
for a retransmit. The InternetFrog site measures how many
bits are received unmangled.

Huh? No way. Like all so-called speed test sites, this site is a poor
indicator of actual performance. In fact, this one seems to be worse
than most others I've tried.

On what do you base your opinions? For some reason, Tier 3
RoadRunner tech support seems to think the InternetFrog site is
a useful measure (more useful than TimeWarner's site and more
useful than DSLreports and Reviews.CNET) of actual information
transfer, i.e. error-free packets received. That is what the % factor
represents - percent of packets received error-free. As corroborated
by a treaceroute, these errors were occurring in the routers just
outside RoadRunner's network. In other words, their backbone
provider was screwing up, and RoadRunner has to get together with
them to get it solved.

Just personal experience over the years. Speed test sites aren't
sophisticated enough to be trusted, other than as a novelty. They have
relatively small files available for download/upload, they typically
don't allow multiple connections, and they're unlikely to saturate
your pipe. Instead, get a program that monitors your transfer rate in
real time, (I use DUMeter but there are others), and find a way to
open multiple connections (either to the same server or to multiple
servers). I use ReGet Pro and have it set to open 8 simultaneous
connections. Some people are able to max out their pipe with fewer
connections, but 8 does it for me, any time of day or night.
The site you provided tells me I'm getting 11.9 Mbps down, but its
files are simply too small for it to realize that I only get 6.5-6.8
Mbps down after you factor out the initial SpeedBoost surge. I'm on a
6 Mbps plan, BTW.

For the vast majority of us, TCP packet retransmissions aren't enough
of a problem to affect throughput speeds, and the problem would have
to be pretty darn severe to drop throughput from 5 Mbps to 1.5 Mbps.

The site was reporting an effective packet rate of 59%. IOW, the
effective speed was dropped by 41% due to packets that had to be
re-transmitted. Couple that with congested local nodes, incorrect
modem parameters, and I end up getting 700 kbps for a "6 Mbps" line.

As much as I hate dealing with TWC as I find them arrogant and rude, |
their tech support staff is first rate. Best I've deal with. And their
in house ability to get down and dirty and know what is going on is way
above what others (in central NC, especially BellSouth) have. I've give
them a bit to get things switched over to their way of doing things. |
