Using a VPN in this digital era is a necessity due to privacy issues and security concerns. But sometimes, using a VPN results into undesired frustrations. You might notice a drastic drop in your connection speed. Although when using a VPN, speeds somehow drop, but a huge drop can indicate a problem. This may be an indication that you might not be using the optimal setup.
A VPN speed is usually measured in 吞吐量 和 潜伏期.大多数速度测试工具只会显示吞吐量，这也是我们在本文中讨论速度时要提到的。
Throughout can also be referred to as bandwidth, and it’s the amount of data that can be transferred in a given period. Its usually measured in megabits per second (Mbps).
另一方面，延迟可以说是数据从服务器传输到设备所需的时间。通常以毫秒为单位。游戏时需要延迟。延迟值越低，VPN 的速度就越快。
With all the above information, let’s dive into ways in which you can make a slow VPN faster. But before we start, you should know your provider’s speed as it helps to know if the VPN is slowing your connection. Below are the tips;
- 更改服务器位置 --VPN 的服务器位置是影响速度的一个重要因素。根据经验，服务器位置的远近会影响 VPN 的速度，甚至会影响其延迟。距离的远近可以用 ping 值来衡量。VPN 服务器位置越远，速度就越低。在这种情况下，ping 值通常较高。为了获得更快的速度，请选择离您最近的服务器，但为了访问全球内容，请避开您所在国家的服务器。
- Look at the server Load – Despite the server location; server load plays an essential role in VPN speed connections. The load is the number of connections directed towards a certain server. If a server is overloaded, its performance decreases and hence its speed allocation will also drop to serve the connections equally. This is the reason why some servers located near you might have lower connection speeds. So before connecting to a server near you, be sure to look at the server load.
- Change the encryption protocols – Protocols ensure security and privacy as they dictate how communication and encryption are done in a VPN. Some protocols offer stronger encryptions with a high overhead, and hence they require more bandwidth than others. This translates to a decreased overall VPN speed. To avoid this decrease in speed, choose protocols which are secure and provide reliable speeds. You might want to choose between OpenVPN UDP and Ikev2 protocols. These protocols offer strong encryptions as well as faster speeds.
- 使用有线连接 --有时 不是你的 VPN 慢，而是互联网/网络连接慢。大多数人喜欢使用 WIFI，因为它提供了便携性，这意味着 WIFI 频段总是超载，性能也会下降。如果您使用的是电脑，请插入网线，您可能会惊讶地发现连接速度会变得如此之快。
- 重启路由器/设备 - 如果不是 VPN 和连接设置的问题，可能是设备的问题。这个问题很难排除，但如果所有其他方法都失败了，这是最后的办法。重启包括路由器在内的设备可能会消除看不见的问题，从而帮助你恢复速度。
如果你的 VPN 连接速度仍然很慢，那么你就应该升级你的互联网套餐，或者换一家 VPN 提供商或 ISP。
