A short answer to this question: VPN connection suppose to reduce your speed because of encryption protocols. VPN will route your Internet traffic through a highly encrypted tunnel, which is why you always feel chocked connection while browsing. If you are using best and legitimate VPN service it will not reduce your connection speed more then 5% to 6% of your regular internet speed.
In some cases, VPN is really a helpful tool when your connection is throttled by your ISP, there are many reasons why ISP throttling your bandwidth, well we will discuss this further in this article. Another benefit is a VPN encryption which enhances your internet connection by providing privacy and security to your connection.

VPN consent to hide IP information and encrypt your internet connection thus, the hackers, spoofing scammers and frauds cannot approach your private information when you are surfing the Internet in a public hotspot or a regular internet connection.
Despite the benefits of VPN, many VPN users are concerned with how VPN distresses Internet speed. So, does a VPN slow down the internet? Essentially, there are more than a few issues that could affect the speed of your Internet whether you are behind a VPN server or not.
The “does VPN make internet slower?” question is not a simple yes or no answer, it can be explained in given steps:
Why VPNs Slow Down The Connection Speed:
Certain VPN providers may claim to increase the Internet connection speed by using VPN, or even assert that they help in bypassing ISP throttling.
Whereas we are not able to answer that question. But if you are using a VPN, it’s not sure that it will or will not slow down your Internet speeds. However, there are a couple of factors which do appear to your connection while being on VPN. You just need to be aware of:
The Physical Location Of The Server:
It’s observed and tested that when you connect to a VPN server which is far away from your physical location, could result in low-speed connectivity. To resolve this issue you can select other nearby servers to enhance the response time. By using some best-recommended VPN providers you could select between huge numbers of servers.
The Quality Of The Encryption:
Type of encryption is also the cause of slow internet connectivity while you are connected through VPN client. There are different protocols which are offered by a VPN provider for handling different types of requests. You can optimize speed by decreasing your privacy and encryption, which means you can try different protocols which allow you different features.
Different Internet Service Providers support various protocols. If you are suffering from slow speed, tune between the protocols i.e. PPTP, L2TP, and OpenVPN. Removing from the protocols also resolves the disconnection issue.
Most commonly VPNs offer 3 types of Protocols, PPTP, L2TP/IPsec, and OpenVPN, which are designed to handle different types of needs by different devices. You should always try to figure out a right protocol for yourself.
Let’s have a look which protocol is best for you!
PPTP (Point-to-Point Tunneling Protocol): By using 128bit encryption method, this protocol offers the best speed but the less secure environment. Also, you can configure this protocol with OpenVPN, which is the plus point.
L2TP-IPsec: In this protocol, you will get high-end security as compared to PPTP. It will slow down your internet speed because of its encrypted tunnel or because of VPN tunneling, but it will ensure you to provide an anonymous connection. The downside would be “hard to figure out with OpenVPN”.
OpenVPN: It’s the best option for all, speed, privacy and security. You may face difficulties in setting things up with Open VPN and you also need another software to configure this setup. OpenVPN is handy to use and deal with speed and security really well.
Load On Servers:
This is the common issue when you are using Free or Trail version of any VPN service provider. It will not allow you to choose or shuffle between the servers list. Therefore, many people remain connected to the same server and in these circumstances, you could certainly face slow connectivity or low browsing experience.
There are even paid VPNs in the market which don’t have sufficient amount of servers to spread the load among them, creating the same issue.
P2P File Sharing:
This is the fact that P2P (Peer-to-Peer) file-sharing is the biggest reason for ISP throttling. A huge amount of downloading through torrent sites makes ISP trackers attentive and they limit your bandwidth.
By using VPN service, you can bypass ISP throttling, but you need to ask your VPN provider that whether they are allowing P2P or not. Otherwise, you will have the same situation as you were facing before VPN connection.
ISP Speed Limitations:
ISP speed limitations could be from your broadband or direct from ISP. I have mentioned above the reason that why and when you could experience such issue. A large amount of downloading torrents is the most common cause of this.
Sometime broadband managers or network managers put some restrictions on your regular Internet connection behind the wall, which put-ons the same situation, and you feel a slow connection.
Interconnection Between The VPN Provider & Your ISP:
Both of them: your ISP and Your VPN are interconnected with each other, they both are involved in limiting your speed.
Testing ISP Throttling:
If your ISP is involved in limiting your bandwidth then you need to check it before connecting the VPN service.
Follow the following steps to check your speed:
- Disconnect VPN
- Visit www.speedtest.net
- Connect VPN
In this process, you will have clear result if there are such speed limits implemented by your ISP.
Particular Routers and 3rd party firewalls also cause speed and disconnection problems. Disable the Router / 3rdparty or Windows Firewall and check the connection consistency and speed. When you set up a VPN connection, make sure your computer’s firewall setting is set then only a VPN can run reliably. Frequently firewall settings do not affect the VPN but affect the CPU speed which can make VPN slow down your Internet connection.
Generally, you may not see such a severe change in internet connection speed when you are using a VPN. The overall speed of your VPN quiet depends on your current internet connection speed. So as long as that is stable, any slowdown will only be a small segment which may not even be noticeable.
