Slow Response Time for Tractor Point
Back to the original post, I agree the site is slower. It has never been very fast. I have a T1 fiber connection and a high end laptop.
Time of day could cause some of the delay, but I usually access the site before 7:00am Eastern and its not any better in the morning that the afternoon. Dave

Slow Response Time for Tractor Point
Dennis,
I pinged the tractorpoint site with a average time of 52ms. A similar ping to Yahoo had an average time of 2ms. A ping to my company server at another location had an average time of 1ms.
It takes me 3 seconds for the site to load, 8 seconds for the discussion boards to load and 8 seconds for a specific board to load.
I am using a T1 fiber connection. I will try the same test at home this weekend.
Regardless, this is an excellent site, keep up the good work. Dave.

Ducati, I question your cable modem speeds.
As you may know the industry standard on cable modem speeds are 128kbps, 256kbps, 512kbps, and 768kbps. The next level available is called a T1 at a speed of 1.544mbps, which is not available in most cable installations. However, when available, a T1 connection can cost up to $1000 dollars per month and require a mult-year contract, compared to about $25 per month for a 512kbps.
T1 connections are considered high data capacity and are point to point fiber using a 10/100 MB ethernet. These are usually business data connections.
A T1 is equivalent to a DS-1 (telephone) and 28 DS-1 equals one 0C -1. This stands for optical carrier at a speed of 51.84mbps, which is now called a SONET (telephone) system.
Ducati, if I am wrong, and you actualy have a T1 connection, I would like to know more about it. I have a T1 at my office and rarely exceed 800kbps. This is a point-to-point fiber. I can ping my business office server at another location in 1ms.
A footnote to those who aren't familar with internet connections:
1. A basic connection is a dialup on a telephone line.
2. The next higher is a DSL connection provided by your telephone carrier.
3. Then you move up to a cable modem as I just discussed.
4. Beyond a cable modem is a point-to-point optical fiber connection called ethernet.

Ducati and Taheide,
I should have known that somewhere on this board there would be somebody with telecommunications experience and I have just enough to be dangerous.
A couple of comments. Taheide, I think we both agree a T1 is 1.544mbps and is equivalent to a DS-1. Twenty eight T1 and/or DS-1 equal 44.763mbps. My understanding, in communication tech language, a DS-1 is 24 non synchronous channels of 64kbps. The T1 is a more common industry standard and equates to the OC-1 as 44.763mbps + 7.104mbps overhead equaling the 51.840mbps.
Generally, for T1 connections a portion can be run over copper, usually, a twisted Cat-5. However, Cat-5 is for short runs with a 300 meter limitation. For higher capacity data transmission it requires point-to-point fiber.
Relating to cable modem speeds, I didn't realize these could be adjusted by the service provider and in a lot of cases you have a non synchronous connection, where the download speed maybe higher than the upload speed.
As I said previously I have a little experience with fiber and telecommunications, but apparently not enough. Thanks for your input. Dave

Taheide,
Thanks for the info and web links, I will check them out. My exposure to T1's, SONET, etc is communications between electrical substations and SCADA dispatching centers.
SCADA stands for Supervisory Control And Data Acquisition. This is computer monitoring and control systems for the electric utility industry.
At present we use a communication protocol called DNP3 and communicate over a 24ct single mode fiber using 10/100mbps Ethernet. Some of our runs are home runs, where others access a SONET hub or a splice enclosure for transmission back to the dispatching center.
Have a Merry Christmas and thanks. Dave

Bvance, this site has stayed on the subject fairly well as opposed to most sites. It is all comupter/internet related. I bet you someone out there has learned something useful on this thread. Dave

Our ramblings about SONET and T1's didn't scratch the surface, this subject gets complicated quick. I will retire in a few years and don't spend the time trying to keep up with technology, like I did a few years ago. I hire young computer gurus, to deal with these issues.
There is a lot to be said for the simple things like seat time on your tractor. Dave
