how test my speed connection

Posted by OurTech Team | Saturday, October 9, 2010 | Category: , |

hello ever one :)


today will see how you can test speed connection :)


her all quetions and the best site to test :)



1.


What is the best way to use Speedtest.net?
Speedtest.net initially recommends a testing location based on what it thinks is the shortest physical distance between you and one of the servers. However, because the Internet does not operate in direct paths, this recommendation may not be ideal. To best utilize Speedtest.net, find the server that provides the fastest and most consistent results and set it as your preferred server in the settings above. Then test against that server frequently to identify trends and make sure you are getting what you expect from your Internet connection. You can review the history of your tests and see how they compare to others in your area.

2.
What must be installed to use Speedtest.net?
Speedtest.net should work in any web browser that supports Flash. At least Flash 8 is required to use the current version of Speedtest.net. Those with a version earlier than 8 will not be able to use the application. JavaScript is also used heavily throughout the site (even to display the Flash), so make sure you don't have it disabled!

3.
Why does the download test work for me, but the upload does not (or vice versa)?
This is usually the result of something installed on your computer that is intercepting traffic between your web browser and the server. Examples of this would be security software from ZoneAlarm, McAfee or Symantec. Try momentarily disabling the software to see if it is the source of the problem. Make sure you don't leave it disabled! Any software firewall should work with Speedtest.net if configured properly. For example with ZoneAlarm you must make sure that none of the boxes are checked in the custom cookie control menu.

4.
Why does Speedtest.net say I need at least Flash version 8 when I already have it?
Speedtest.net uses the very popular JavaScript package SWFObject to detect your Flash version. If you are certain that JavaScript is enabled, then there could be an error in your Flash installation. This problem is usually solved by uninstalling and then reinstalling Flash.

5.
Can I remove past results from my history?
Yes! You can hide past results using the panel labeled 'Hide Results Before' on the Your Results page. Simply select a date by clicking on the small calendar icon. The page will be refreshed and only display results of tests taken since the date you selected. You can also do this for for each IP address you have used on the Your Summary page. The entire summary including your best result image will instantly reflect ignoring results prior to the date you select.

6.
Can I download my past results in a file?
You sure can! This is done via the "Download in CSV Format" link above the Results History section on the Your Summary page. Note that it downloads all results for the IP address data you are currently looking at.

7.
Does kb/s and kbps mean kilobits or kilobytes, and can I change the the measurement being used for speeds?
We use kb for kilobit and KB for kilobyte throughout the site. So unless you see it in upper case, then it means kilobits. You can change it to other measurements in the settings panel found at the top left of every page. Everything on Speedtest.net (including result images) will utilize the setting you choose.

8.
Why don't my settings changes save?
Speedtest.net uses web browser cookies to save your settings. You likely either have cookies disabled or a third-party application is blocking them.

9.
How does Speedtest.net know where I am?
Your location is determined based on your IP address. Speedtest.net uses GeoIP data from MaxMind to position you on the map and determine your closest server. You can learn more about the MaxMind GeoIP data here.

Back to top
10.
Why does Speedtest.net think I am somewhere that I am not?
While the information in MaxMind's GeoIP databases is very accurate, it is not perfect. You can see exactly where they think you are here. The data is updated monthly, so there is always a chance that an inaccurate record gets corrected next month.

How is the distance between me and the testing server calculated?
Mathemagics! We use some fancy geometry to measure the distance between two points on a sphere. One point is the latitude and longitude of the server while the other is you.

Back to top
12.
Why don't I get my best speeds to the server that is closest to me?
The Internet does not operate in direct paths. A server might be physically close to you, but the route to get it it could actually travel to another part of the country and back before getting to it. The server with the shortest "network distance" should end up being your best, and while this is often the closes one geographically it sometimes is not. Try several servers to find your best one.

13.
Why does network distance to a server affect throughput?
You have likely noticed that downloading from a local server location is faster than a distant one. This is because the TCP window (and therefore HTTP transfers) is not optimized for the increased latency that comes from an increase in distance.

Back to top
14.
TCP window - say what?
HTTP is technically bound by the TCP "congestion window" which determines how many packets can be sent at one time. The larger the window size, the higher the throughput. Latency directly affects this because slower responses will create delays between packet sends.

15.
What is ping and how do you measure it?
Ping on Speedtest.net is a bit different than a traditional command-line ping which uses ICMP. We are measuring the time it takes to get a response for an HTTP request sent to the server. The number will be higher than an ICMP ping, but the relative value to other tests is still very useful. The server you ping the lowest to will usually be the server that provides the most accurate bandwidth measurement.

16.
How are global and country ranks calculated?
We first calculate where your download speed ranks, and then we do the same for upload. The overall rank is the average of the two. This is done at both the global and country levels. Only your best test scores are used for the ranking. Note that ranks done per IP address. So if you IP address changes, your rank will change as well. You can look at results for past IP addresses though to see the rank of each. You can "reset" your rank by setting an ignore date.

17.
Why are my test results not showing up in my history?
Past tests are shown per unique IP address. At the top of Your Results, there is likely a drop menu for your IP address. Check to make sure you are viewing your current IP address.

18.
Why have you incorrectly identified my Internet provider, and how can I get it fixed?
We also use MaxMind's data to identify your Internet service provider. Like locations, this is not always accurate. If it is incorrect, then hopefully it will be fixed in the next month or two. You can see who they think your ISP is here. If you work at the ISP and are the owner of the netblock, then you can email MaxMind the corrected details.

19.
How are the Global Stats averages calculated?
We first calculate the 95th percentile speed in each direction for every unique IP address that has tested at Speedtest.net. These numbers are then averaged together for each geographic level (both overall and per ISP).

20.
Won't locations without a local testing server be at a disadvantage in the rankings?
Unfortunately yes. But our goal is to get quality testing servers in every major city around the globe. If one does not exist in your region and you can provide one, please do so. Since the average speeds are based on only the top speeds for IP addresses, a new host in a region can quickly boost the local rankings.

Back to top
21.
Why is my region, city or ISP not listed in the Global Stats data?
A minimum number of unique IP addresses is required before a region, city or ISP is listed in the Global Stats data. The minimum is currently 25 IP addresses at the city level and 100 IP addresses at every other level.
22.
Can I get a speed test application for my own website?
Yes, there are several options which we offer that allow you to operate a speed test application on your own server and web site. The first is Speedtest.net Mini, a free application that must be renewed monthly and is best suited for low-volume use such as on a personal home page or a site for small organizations such as a group of gamers or a hobby site. If you require a permanent speed test with detailed reporting and a variety of options including your own branding, please head visit the Ookla Net Metrics web site. Be sure to check out the on-line gallery to see many examples and perhaps get some ideas.
23.
Why do I have an invalid license key error message?
This is a known issue with many Internet Explorer 6 users. An upgrade to either of the latest two major revisions of the application (IE7 and IE8) will most likely resolve the problem. If upgrading is not an option for you, unfortunately IE6 is no longer supported. There are many other websites that also require an upgrade to IE7 or IE8 as there are a large number of known bugs with IE6 that are only resolved with an upgrade. If your IT department will not allow for an upgrade I would definitely recommend that they consider implementing one soon for global compatibility.

Why are my test results outrageously fast?
This is usually the result of something installed on your computer that is intercepting traffic between your web browser and the server. Examples of this would be security software from ZoneAlarm, McAfee or Symantec. Try momentarily disabling the software to see if it is the source of the problem. Make sure you don't leave it disabled! Any software firewall should work with Speedtest.net if configured properly.
