<h2>How does this work?</h2>
|
|
<p>
|
|
The speedtest measures the maximum download speed from pixeldrain's
|
|
servers to your computer. This speed is not affected by the daily
|
|
download limit for free users.
|
|
</p>
|
|
<p>
|
|
The speed measured is the maximum speed reached for two continuous
|
|
seconds during the test. The normal test has a time limit of 12
|
|
seconds and the long test 30 seconds. When the maximum speed has not
|
|
changed for a third of the test duration (4 or 10 seconds) the test
|
|
will end and the result will be final. The long test will use much
|
|
more bandwidth, so if you're on a cap it's recommended to use the
|
|
normal test.
|
|
</p>
|
|
<p>
|
|
The speed gauge uses a logarithmic scale, which means that each
|
|
datapoint is 10 times more than the last one.
|
|
</p>
|
|
|
|
<h2>What do the numbers mean?</h2>
|
|
<p>
|
|
The first number is the download speed in bytes per second. This is
|
|
useful for estimating how long a file download will take.
|
|
</p>
|
|
<ul>
|
|
<li>1 kB = 1000 bytes</li>
|
|
<li>1 MB = 1000 kB</li>
|
|
<li>1 GB = 1000 MB</li>
|
|
<li>etc..</li>
|
|
</ul>
|
|
<p>
|
|
The second number shows the download speed in bits. This is usually
|
|
the speed your ISP advertises to you. This number is equal to the
|
|
first number multiplied by eight, because there are eight bits in a
|
|
byte.
|
|
</p>
|
|
<p>
|
|
The third number shows the latency to the pixeldrain servers. This
|
|
is dependent on how far you are removed from the closest pixeldrain
|
|
server. The lower the latency the faster your downloads will be,
|
|
generally. The number shows request latency and not ping latency.
|
|
HTTP requests have some overhead which means this latency number
|
|
shows multiple round trips instead of one.
|
|
</p>
|
|
<p>
|
|
The last number shows how much data the speedtest was able to
|
|
transfer in the duration of the test.
|
|
</p>
|
|
|
|
<h2>Why is the speed different from other speed tests?</h2>
|
|
<p>
|
|
Most speed tests have servers in datacenters which are located very
|
|
close to your home. They are also connected directly to your ISP
|
|
which means that the ISP does not have to pay for the bandwidth
|
|
because it stays within their network.
|
|
</p>
|
|
<p>
|
|
Pixeldrain does not have this luxury. Because our budget is very
|
|
small we are only able to afford the cheapest bandwidth available.
|
|
This means that the data has to travel further and is more likely to
|
|
be throttled.
|
|
</p>
|
|
<p>
|
|
VPN services also add overhead to your connections, which lowers
|
|
effective download speed. VPNs using OpenVPN lower your download
|
|
speed by approximately 17.2%, and VPNs using the more modern
|
|
WireGuard protocol lower your download speed by approximately 4.5%.
|
|
To get most accurate results make sure you have any VPN services
|
|
turned off.
|
|
</p>
|
|
<h2>How do I read these results?</h2>
|
|
<p>
|
|
If the speed is a lot slower than your usual downloads it can mean
|
|
two things.
|
|
</p>
|
|
<ol>
|
|
<li>
|
|
Your ISP is limiting the connection speed to pixeldrain's
|
|
servers
|
|
</li>
|
|
<li>
|
|
The pixeldrain servers are overloaded
|
|
</li>
|
|
</ol>
|
|
<p>
|
|
Number two is usually not the case, when that happens I will
|
|
<a href="https://twitter.com/Fornax96">tweet about it</a>.
|
|
Unfortunately there is nothing I can do about the first scenario. I
|
|
might be able to get more servers and better bandwidth if the site
|
|
gets many more subscribers, but for now that's out of reach.
