How do I use your Speed Test?

I find your Speed Test page confusing. It's just a bunch of links, with no instruction on how to actually obtain a speed from the downloads. How do I use this?

Our Speed Test is conducted using the 'wget' command from your local machine, run against the URLs that the links on the Speed Test site. What you do is copy the URL for each link you wish to test and run:

wget <url for the datacenter you are testing against>

where <url for the datacenter you are testing against> is the URL for the datacenter you are testing. For example:

wget http://speedtest.newark.linode.com/100MB-newark.bin

Alternatively, to test all of the datacenters at once, you can use a script, such as:

#!/bin/bash

readonly -a locations=("atlanta" \
                       "dallas" \
                       "frankfurt" \
                       "fremont" \
                       "london" \
                       "mumbai1" \
                       "newark" \
                       "singapore" \
                       "tokyo2" \
                       "toronto1")

readonly -a filenames=("atlanta" \
                       "dallas" \
                       "frankfurt" \
                       "fremont" \
                       "london" \
                       "mumbai" \
                       "newark" \
                       "singapore" \
                       "tokyo2" \
                       "toronto")

declare x=0

for i in "${locations[@]}"; do
    wget speedtest."${locations[$x]}".linode.com/100MB-"${filenames[$x]}".bin
    x=${x}+1
done

This script will test every one of our datacenters speed from your location. From there, you can decide which datacenter will best suit your needs. To run it, simply copy/paste the code into a text editor and save it with a filename like 'speedtest.sh'. You then need to give the script execute permissions:

chmod 755 speedtest.sh

From here, you can invoke the script by navigating to the directory in which it lives and running:

./speedtest.sh

where 'speedtest.sh' is whatever name you gave to the script.

I recommend running these tests from an area where most of your customers will connect to your server from, so you can ensure that they are provided with the best experience.

Please Note that while running all of the tests, that you will want to avoid streaming content or doing anything else on your network to avoid skewing the test results.

macOS / Linux

On macOS, you can copy the script below into your clipboard and then open a terminal. Because you can't have two things in your clipboard at once, you will need to type the following:

pbpaste > speedtest.pl

Under Linux, you will need to open your favorite text editor and paste the text into a new file called speedtest.pl and then save it.

You can then make your script executable and run it:

chmod 755 speedtest.pl
./speedtest.pl

Here is the script:

    my $hh = int($elapsed) / ( 60 * 60 );
    my $rest = int($elapsed) % ( 60 * 60 );
    my $mm = $rest / 60;
    $rest = $rest % 60;
    my $ss = $rest;

    print "$regions[$i]:   ";
    printf ("%02d:%02d:%02d.%02d   %7dms\n", $hh, $mm, $ss, $cc*100, $elapsed*1000);
}

Windows

In Windows things are a little more complicated because there only native command to download files on all versions of Windows (beginning with Windows 7). You can copy and paste the following script into a batch file by opening a command prompt and typing:

notepad.exe speedtest.bat

Make sure you save the file after pasting.

Run the batch file by typing speedtest.bat from the commandline.

I believe there's a typo for the mumbai datacenter. Currently, wget returns a 404 for its speedtest. The URL should be http://speedtest.mumbai1.linode.com/100MB-mumbai.bin rather than http://speedtest.mumbai1.linode.com/100MB-mumbai1.bin.
Note the correct filename is 100MB-mumbai.bin, not 100MB-mumbai1.bin. The filename entry "mumbai1" in the script should be changed to reflect this.

ySApt29pe8GA, you are correct that there is a typo in the script. I will reach out to get this corrected. I have updated the other two scripts to include the Toronto and Mumbai datacenters.

@ySApt29pe8GA, thank you for pointing that out. I've corrected the script, and everything is working correctly now when I run it:

Another script, because scripts are all awesome! This script will emulate a larger download, if you wanted to test a longer sustained download time. You will need to edit the datacenter name to the datacenter that you wish to test. I used Dallas for the default:

#!/bin/bash
echo "This will test an emulated 10GB Download. Feel free to edit the loop to change the download size, and watch your disk space disappear!"
test="0"
while [ $test -ne 100 ]
do
  wget -O test$test.bin  http://speedtest.dallas.linode.com/100MB-dallas.bin
  ((test=test+1))
done

I would also suggest running this script with time before it, as this should give you an estimate easier. Assuming the script was saved as Speedtest.sh:

time ./Speedtest.sh
