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.
ISP 限制
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.
路由不良
由於各種原因和其他業務決策，您的 ISP 可能會實施可能不利於您的速度連接的路由連接。例如，較長的路由將導致連接速度下降。使用 VPN 時，其中一些路由連接不會體驗到，因為 VPN 會中斷它們並將您連接到最近的伺服器。反過來，這將提高互聯網速度。
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.
伺服器連接。
伺服器越遠，連接速度越慢。此因素取決於其他因素，並且該規則可能並非始終有效。當較近的伺服器過載並導致性能問題導致連接速度變慢時，可能會發生這種情況。為了更好的速度。檢查伺服器在連接到伺服器時是否過載。您可以通過檢查回應時間來瞭解這一點。
免費/付費專用專用網路
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.
