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 輸送量 和 延遲.大多數速度測試工具只會顯示輸送量，這就是我們在本文中討論速度時所指的內容。
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，延遲可以說是數據從伺服器移動到設備所需的時間。它通常以毫秒為單位。遊戲時延遲是必需的。延遲值越低，VPN 的速度越快。
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;
- 更改伺服器位置 – VPN 的伺服器位置是速度的重要因素。根據經驗，伺服器位置的接近程度會影響VPN的速度甚至延遲。可以使用 ping 值測量鄰近度。VPN伺服器位於越遠，您可能獲得的速度就越低。通常，在這種情況下，ping 值更高。為了獲得更快的速度，請選擇您附近的伺服器，但避免使用您所在國家/地區的伺服器，以便訪問全球內容。
- 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.
- 使用有線連接 – 有時不是您的 VPN 速度慢，而是互聯網/網路連接。大多數人更喜歡使用WIFI，因為它提供了便攜性，這意味著WIFI頻段將始終過載，其性能將下降。如果您使用的是計算機，插入LAN電纜，您可能會驚訝於連接的速度。
- 重新啟動路由器/設備 – 如果不是 VPN 和連接設置，則可能是您的裝置有問題。此問題很難解決，但如果所有其他方法都失敗了，這是您最後的手段。重新啟動設備（包括路由器）可能會消除看不見的問題，從而幫助您恢復速度。
如果您的 VPN 連接仍然很慢，是時候 升級 您的互聯網套餐或 切換到 其他 VPN 供應商或 ISP 了。
