How to Test Network and Internet Latency (Lag) in Microsoft Windows
Putra Soliman

Steps

  1. 1
    Go to Start > Run and type cmd. You can also search for cmd.exe in the Windows Search function.

    DataCenter Cloud Computer

     Servers Workstations Motherboards w/ Intel® Xeon® Processor E5 Series
    Supermicro.com.tw/NetworkStorageHPC
  2. 2
    Press OK to launch Windows Command. This is the default command-line interface for Windows.

  3. 3
    Test the loop-back address.
    • Type ping 127.0.0.1 (it is the same for every computer, so you do not need to change this). This will test your computer's network chip, not your modem, router, or Internet connection.

    • Press Enter to begin pinging.

    • Place -t at the end of the command to perform continuous testing.

    • To exit continuous testing, press Ctrl+C.

    • Place -n 20 at the end of the command to send 20 pings. Replace the number 20 with any value (the value will be limited to a 32-bit or 64-bit integer).

    • If everything is correct, you will see something like:

    • Look at the ping statistics. They should report a 0% loss.

    • Keep an eye on the response time, as it represents the connection's latency between you and the server. Double digit values (such as 50ms, or lower) are very good. This varies drastically depending upon where the server is in relation to your computer. Generally, most connections should have latency less than a few hundred milliseconds. If there is no network connection, you will see the output "Request timed out" repeated.

  4. 4
    Test your local gateway. Find your default gateway's IP address:

    • Type ipconfig in the command prompt window.

    • Press Enter. The command prompt will then display the output from the ipconfig command.
    • Find the listing for "Default Gateway". This is the IP you can use in a ping to test the connection between your computer and your router or ISP.
  5. 5
    Test beyond your local network. Test the connectivity of your modem, router, network, or internet connection by using an IP address on the Internet.
  6. 6
    Check domain name resolution. Instead of an IP address, type in a site's domain name, such as www.google.com. Pinging a domain name tests your computer and network's ability to resolve network names (translating them to IP addresses).

  7. 7
    Measure network and internet performance (Windows NT, 2000, XP, and Vista only). Use the tracert command to measure the response of each hop in a network path. Your connection to any one server will require multiple "hops" between other servers and networking components. The fewer number of hops, the better. Most connections to a server on the Internet will include at least a dozen hops. To test:
    • With the command prompt open, type tracert xxx.xxx.xxx.xxx, replacing xxx.xxx.xxx.xxx with an IP address on the internet.
    • Press Enter and watch as each hop is pinged and logged. The first ping should be your computer, modem, or router, and the last ping should be your target address.
    • Notice that the response time for points farther away from you will be greater than those closer to you.

CUSTOMIZING WINDOWS RUN COMMAND

Customizing Windows Run Command...

If you are like me you use windows run command all the time.  I hate using the mouse to point and click a shortcut on the start menu.  WIN-R are probably the two most over used keys on my keyboard.  After thinking about if awhile I hunted down how the run command works.  It turns out that it makes a call to ShellExecute, which I guess is not too surprising.  The next thing I wanted to find out was exactly how the commands are resolved. The following is an ordered list of how they are resolved ([1]):
  • The current working directory
  • The Windows directory (no subdirectories are searched)
  • The Windows\System32 directory
  • Directories listed in the PATH environment variable
  • The App Paths registry key
Naturally the next thing I wanted to do was customize existing commands or add new commands so I do not have to type as much (standard lazy approach).  After examining my options which were to put the executable in one of those paths (since it only locates executables and not shortcuts), modify the path environment variable or add a key to App Paths. The App Paths option seems to be the easiest and most flexible to me.  Here is a layout of what you need to do to add an App Paths entry ([1]):
HKEY_LOCAL_MACHINE
    SOFTWARE
        Microsoft
            Windows
                CurrentVersion
                    App Paths
                        file.exe                           (Default) = The fully-qualified path and file name
                           Path = A semicolon-separated list of directories
                           DropTarget = {CLSID}
Disclaimer: Modifying the registry can cause serious problems that may require you to reinstall your operating system. I cannot guarantee that problems resulting from modifications to the registry can be solved. Use the information provided at your own risk.
The minimum needed to add a new entry is to add the key file.exe where file is the string you want to type into the run command and to add the Default entry which is the fully-qualified path to the file you want to execute. Note that even it the file you are going to reference isn't an exe file you still need to put the .exe on the key. Here is a sample registry file that I created to add a shorter keyword for Internet Explorer:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\ie.exe]
@="C:\\Program Files\\Internet Explorer\\iexplore.exe"
After entering that entry into the registry I can simply type “ie” at the run command to open internet explorer.

RUN++
Run++ is a replacement for the windows run command. Currently the windows run command is very limited it only provides a drop down list of the last 26 typed commands and a auto complete functionality for the file system and browser history as described here. Run++ provides the following feature set:
