How to check the upload and download speeds of my server?

I bought a server, and I need to check its Internet connection (speed).

Is there an easy way to do this?

I googled but found nothing ...

I have done this:

<?php

$link = 'http://speed.bezeqint.net/big.zip';
$start = time();
$size = filesize($link);
$file = file_get_contents($link);
$end = time();

$time = $end - $start;

$speed = $size / $time;

echo "Server speed is: $speed MB/s";


?>

Is it correct?

Try:

<?php

$link = 'http://speed.bezeqint.net/big.zip';
$start = time();
$size = filesize($link);
$file = file_get_contents($link);
$end = time();

$time = $end - $start;

$size = $size / 1048576;

$speed = $size / $time;

echo "Server speed is: $speed MB/s";


?>

If you have a remote desktop, then install a web browser and go to speedtest.net and check the speed.

If not, how can you test the download speed of your server:

  • log in as root
  • type wget http://cachefly.cachefly.net/100mb.test
  • you will see something like 100%[======================================>] 104,857,600 10.7M/s- 10.7M / s - download speed.

If you have more than one server, you can check the download speed by transferring files between the two servers.

script, :

$start = time(true);

$fileSize = '10240'; // if the file size is 10MB

for ($i=0; $i<10; $i++) {
    file_get_contents('the_url_of_a_pretty_big_file');
}

$end = time(true);

$speed = ($fileSize / ($end - $start)) / $i * 8;

echo $speed; // will return the speed in kbps
