VPN’s primary functions involve providing security and privacy. Other accrued benefits include unblocking and gaining access to restricted content. But that’s not all, depending on certain factors, a VPN can increase or decrease your internet connection speed. As a rule of thumb, a VPN is supposed to reduce your internet speed due to server connections and encryption overheads. But at times you can experience an increase in speeds. We are going to look at factors which influence this phenomenon.
互联网服务提供商节流
互联网服务提供商节流This is the most common factor that influences an increase in internet speeds when using a VPN. Most times, ISPs want to ensure that their customers are satisfied with their service especially when they don’t have adequate infrastructure or want to make a profit. For instance, some users may use a lot of bandwidth, and this may create a deficit for other users who don’t take up much bandwidth. Example, users who stream, play online games and torrent use a lot of bandwidth. An ISP can choose to throttle the speed for such tasks to ensure everybody on the network has average speed. Other times, an ISP may throttle speeds to some services due to business conflicts. For instance, Netflix may be throttled if the ISP offers its streaming services.
ISPs throttle your internet by seeing what you are doing online. This is easy as they monitor all your internet traffic. Throttling may result in a drastic drop in your internet speed, let’s say you may experience 10mbps whereas you have paid for 15 Mbps. When using a VPN, your ISP will not see what services you are using that are taking more bandwidth and hence they may not throttle what they can’t see. A VPN achieves these by encrypting and obfuscating your internet traffic.
路由不佳
由于各种原因和其他业务决定，您的 ISP 可能会实施不利于您的连接速度的路由连接。例如，较长的路由会导致连接速度下降。在使用 VPN 时，有些路由连接就不会出现，因为 VPN 会打破这些连接，将你连接到最近的服务器。这反过来又会提高网速。
Apart from the above factors, a VPN is supposed to decrease your internet speed but by a smaller percentage. If you are experiencing drastic drops in speed, its because of the following factors;
加密
The stronger the encryption protocol, the slower your VPN connection will be. Strong encryptions result in higher encryption overheads on your internet speed. To experience both speed and security, use a balanced encryption protocol such as OpenVPN UDP. This protocol is suitable for streaming.
服务器连接。
服务器越远，连接越慢。这一因素取决于其他因素，而且这一规则并非在任何时候都适用。当较近的服务器负载过重时，就会出现性能问题，导致连接速度变慢。为了获得更好的速度。在连接服务器时检查服务器是否超载。您可以通过检查响应时间来了解这一点。
免费/付费 VPN
A free VPN service is bound to experience slower connection speeds than a paid VPN. This is due to some various reasons such as more users connected to it, poor optimization and inadequate infrastructure.
