Test your internet speed
--
Run a speed test without your VPN.
Testing internet speed without a VPN helps you get a baseline to compare against your speed with a VPN
Turn on your VPN and run another speed test.
Testing internet speed with a VPN involves turning on your VPN and running a speed test again after checking your regular internet speed.
VPNs can slow things down, so this test shows the difference.
When doing tests please, Close programs and applications that require a lot of bandwidth (streaming sites, YouTube, torrents, etc.)
When testing with and without vpn, be sure to select the same destination server in the speed test at the top of this page.
Try These Quick Fixes
A closer server might be faster.
Different connection settings can affect speed.
Wi-Fi can be unreliable, try an ethernet cable.
Sometimes a simple restart can clear things up.
VPN speed test measures your internet speed through three key metrics : download speed, upload speed, and latency (ping)
Indicates how quickly data from the internet reaches you, measured in Mbps (megabits per second). Higher download speeds mean faster streaming, downloading, and browsing.
Measures how fast you send data to the internet, also in Mbps. High upload speed is important for activities like video calls and live streaming.
Shows the time it takes for a data packet to travel from your device to a server and back, measured in milliseconds (ms). Lower ping means faster response times and better performance, especially in online gaming and real-time applications.
* Tip : Use a paid VPN for better speed and security, as free VPNs often lack these qualities.
Your VPN speed can be influenced by several factors. Here are the key ones
This is the biggest culprit! Test your internet speed without a VPN first.
Connecting to a server in another country adds travel time for your data. Choose a closer server for better speeds.
Too many users on one server can slow things down. Try a different server location.
Encryption adds a bit of overhead, but a good VPN shouldn't slow you down much.
Some protocols are faster than others. Try switching protocols if your VPN allows it.
Peak internet usage times can also affect VPN speed.
Even with a good VPN, your internet might slow down a bit. Here's what you can try to fix it
Sometimes, switching to a different server can help. VPN providers often have multiple servers in popular locations.
Different protocols can affect speed. For instance, switching between Targon and Neon might improve your connection.
If the server you're connected to is far away, try a closer one. This can reduce latency and improve speed.
Extra tabs and apps can use up bandwidth. Close what you don't need to free up resources.
Sometimes, a simple restart can fix speed issues. Turn off and on your router and device, then check your speed again.
If problems persist, consider changing your VPN or internet provider.
A slow internet connection will affect VPN speed.
Closer servers provide better speeds.
Overloaded servers can slow down your connection.
Some ISPs slow down VPN traffic.
Use up-to-date equipment and drivers for the best speeds.
Yes, all VPNs have the potential to slow down your internet. At ZeroMarksVPN , we optimize our service so that you’ll barely notice a difference.
Several factors can influence how much a VPN slows down your internet, from the quality of your VPN service to the physical distance between you and the server. However, good VPNs shouldn’t decrease your speeds beyond 10%-20%. Let’s take a look at the most important factors.
There are several reasons why current VPN speed tests might not be accurate
Most tests are done manually, so they don't capture a broad range of conditions.
Tests might be done at different times, not accounting for peak usage hours.
Wi-Fi and public networks can be unstable and affect test results. Ethernet connections are best.
Slow internet or a network bottleneck can mask the true VPN speed. Tests should use high-speed networks.
Browsers and extensions use resources that can affect test results. Consider command-line tests.
Cloud storage, antivirus, etc. running in the background can slow things down. Disable them for testing.
Some VPN protocols, like OpenVPN, can max out a CPU core, affecting test accuracy.
When utilizing third-party tools like Ookla for VPN speed testing, several considerations must be kept in mind to ensure accurate results:
Ookla relies on GeoIP databases like MaxMind to determine client locations, which may suffer from inaccuracies. VPN providers expanding their server networks can exacerbate this issue, leading to incorrect city information. While Ookla usually recommends servers in the same country as the VPN server, city information discrepancies can affect accuracy.
Inconsistent Test Server Speeds
Since the speed test tool runs on a VPS, resource sharing with neighboring systems can lead to performance declines. VPS providers' fair usage policies may limit resources assigned to the speed test VPS, affecting performance.
Outliers significantly differing from other observations can skew averages. Removing the top and bottom 3 percent of data helps mitigate this issue, ensuring more accurate results.
Utilizing the results can create reports, including histograms, mean and median download speeds, percentile , and statistical tests. These reports help evaluate test distribution over time and VPN performance stability.
Advanced techniques like the Wilcoxon-Mann-Whitney test compare VPN providers without assuming normal distribution, considering shape, spread, and median differences. This helps identify winners based on statistical significance and median speeds.
Free
VPNs can be tempting, but saving money often means
sacrificing
your privacy.
A free VPN service does not have the resources to provide a
top-notch service.
