Best way to test latency?

What is the best way to test my latency? Is the one on testmy.net a good, accurate one? It gives you locations to choose from for the test -- Miami, NY, Tokyo, google, amazon, etc. Which location should I use? I'm in central Florida. How much latency should I expect on my Hughes connection?

Re: Best way to test latency?

Yes, 600-700 is normal for satellite internet. 

 

Keep in mind that websites add to the delay because they have so much stuff on them that needs to load, such as images or videos.  So on top of the normal server to server delay, you will have added delay from website content.

Re: Best way to test latency?

You can expect an average latency of between 600 and 700 ms with satellite internet, though it varies widely due to many factors. 

 

To test latency, use the tracert command.  EDIT: Trace routes to the servers of the sites you use  (ex.: netflix.com; amazon.com, etc)

 

The Testmy.net latency test is completely unreliable, especially for statellite internet.

Re: Best way to test latency?

I'm using a chromebook, I googled 'how to get a command line on a chromebook (ctrl+alt +t does it). Going by the instructions on the link you provided, I typed: tracert netflix.com. Also tried: tracert google.com. In both cases the message back was: ERROR: unknown command: tracert. What am I doing wrong? I'm doing this via wifi, but I'm very close to the hughes HT2000 wifi router. Does it matter if I'm on wifi vs. ethernet cord?

For a chromebook, try this:  https://www.howtogeek.com/170648/10-commands-included-in-chrome-oss-hidden-crosh-shell/

 

I think what you will need is a tracepath. There are instructions there on how to run it. 

 

EDIT:  instructions from another site:

 

How to Traceroute from a Chromebook

 

  • Get the command prompt by pressing Press CTRL + ALT + T
  •  Type tracepath domain.com and hit enter (replace domain.com with the website or IP you want to trace route to.)

 

Example:

tracepath amazon.com

Re: Best way to test latency?

Ok, I discovered that for chromebook, the command is tracepath instead of tracert. That worked, and I got results, but I don't know how to read them, and I don't see any guidance on that link you provided about how to read the results. And what is the typical amount of latency for Hughes?

Post a screenshot of your results, please.

 

Like I said before, the average latency for satellite internet is between 600-700 ms.  This may vary based on many factors.

Ughh, I can't figure out how to paste a screenshot here. I can copy a screenshot to clipboard and then paste (ctrl+v) it into a google doc no problem, but when I try to paste into this message window, nothing happens.

Re: Best way to test latency?

  • You will need to upload the screenshot. 
  • Once you take the screenshot, you need to save it to your Chromebook. 
  • Then you come back here, and start writing a response. To upload the image, click on the "photos" icon (see screenshot below), then follow the instructions to upload the image.

Re: Best way to test latency?

I've tried everything I can think of to paste a screenshot here, and googled for solutions, and came up with nothing. What the hey is going on?
