Problems with Verizon High Speed
-
Hi All, Anyone having issues with Verizon High Speed? I'm having interemittent service problems. When I contact their tech support, they are blowing smoke up my ass. WTF... I'm at the point where I am splitting hairs on service levels. They claim an 860KB download, but I'm only realizing 730KB due to packet loss in their network*. Jeff * The problem is in one of three places in my local testing. My testing involves FTPing a file from University of Maryland to Baltimore (my house). There a three network segments: My LAN, Verizon's network, or Cogent's Network (University of Maryland). Maryland has an OC-12 from Cogent, so they are proably not dropping packets. My LAN is GB Ethernet, so I am probably not dropping packets.
I have FiOS and am having no issues at all. I love it. I have the 20\5 service and am able to use it at the advertised speeds regularly. I have to admit that at first it was much slower that it should have been and when I called the technical support department they told me to run a TCP optimizer tool and I laughed at the, I have run them before and never saw a significant effect from it but I ran it this time and man oh man did it help. I guess when you are up around the 20 mark the help of things like the TCP window really does matter. Using Vista on the other had was really having some issues because the optimizer did not work there. The stacks on Vista are supposed to be self tuning, but I was never able to get Vista working up to the full speeds. XP screams on FiOS though. Enough to get me looking into getting the symmetrical 20\20 service.

The stacks on Vista are supposed to be self tuning ... more like self tuning out X|

I've read a lot about auto tuning. Chris and I have had some sidebars on the topic. Here's what I wrote to Chris. Jeff In 1981 (TCP's birth) the maximum window size was 65536. Since then, Internet engineers have moved mountains to get that size increased. They changed TCP's header to add an option to scale the size so that larger window sizes are available. ... This is the first time I've been able to examine Auto-tuning in detail. I have not been to a Server 2008 boot camp to get the spin on it from Microsoft or a certified MCSE instructor. But it seems others have developed a disdain for it also:
And if you are using Vista, you have bigger problems. Do all your testing with XP if you still can. The auto-tuning in Vista... [1]
I find it down right arrogant of Microsoft to deploy this as default behavior. I've got a somewhat dirty link, and this tuning is killing performance. Worst, there's nothing I can do to change it because the configuration lies elsewhere (i.e., another's protocol stack). In "Next Generation TCP/IP Protocols and Networking Components", Microsoft states:
...in testing performed internally at Microsoft, backup times for large files were reduced by almost half for a 1 gigabit-per-second connection with a 50 millisecond round-trip time (RTT). [2]
50 ms RTT. WTF is going on in Microsoft's mind??? They projected world wide performance based on testing a large file in a lab??? Where I am, 25 ms might get you three or four routers beyond your immediate network (25 ms * 2 = 50 ms RTT) [3]. What about the other 15 or so hops???

You'll never realize the full 860kb. They call it "overhead", and what it amounts to is fraudulent advertising. They say you'll get "up to" 860KB, and that absolves them making sure that you realize that speed. All of the ISPs do it.

That's an image I don't need... :doh:

I've never ever worked anywhere where there has not been someone who given the choice I would not work with again. It's a job, you do your work, put up with the people you don't like, accept there are probably people there that don't like you a lot, and look forward to the weekends. - Josh Gray.

Not sure why you're being down voted... here's a bump.

People that state the truth are often denigrated in the press. :)

I'm surprised you never heard the expression before, it's not that uncommon...

Nope. English isn't the first language where I live, and if it's a relatively recent expression that is only ever spoken and not written, chances are I didn't come across it.
Cheers, Vıkram.

It's been around for a while I first heard it at least a decade ago, googling comes up with multiple dubious origin stories.
