Performance Tips for Your PC VPN

To get the best out of your VPN connection, consider these performance tips:

• Choose a Nearby Server: Connecting to a server geographically closer to you will generally result in lower latency and faster speeds.
• Experiment with Protocols: While VLESS is excellent, sometimes switching to Shadowsocks or another protocol might yield better results depending on network conditions and censorship methods. FastNeo VPN often provides various protocol options for this reason.
• Use Wired Connection: Ethernet offers more stable and faster speeds than Wi-Fi, especially for demanding tasks.
• Disable Unnecessary Apps: Close applications that consume significant bandwidth in the background.
• Update Your Client: Keep your VPN client and operating system updated to benefit from performance improvements and security patches.
• Check Server Load: Some VPN providers display server load. Choose less congested servers if available.
• Adjust Encryption Settings (Advanced): While VLESS is generally efficient, some protocols allow for different encryption ciphers. Lighter ciphers can sometimes offer faster speeds at a slight theoretical security trade-off (though modern ciphers are generally robust).

Split Tunneling: Control Your Traffic

Split tunneling is a valuable feature that allows you to decide which applications or websites use the VPN connection and which access the internet directly. This offers several benefits:

• Optimized Speed: Route bandwidth-intensive activities (like streaming local content) outside the VPN to maintain high speeds, while sensitive traffic remains encrypted.
• Access Local Network Resources: Access local network devices (printers, shared drives) while simultaneously browsing the internet securely via the VPN.
• Bandwidth Saving: Reduce the amount of data routed through the VPN server, potentially saving bandwidth if your VPN plan has limits.

How to Configure Split Tunneling:

The implementation of split tunneling varies by client. Hiddify and NekoBox/NekoRay often provide rule-based routing or application-specific settings. You typically define rules for:

• Excluding Apps: Specify applications that should bypass the VPN.
• Including Apps: Specify only certain applications to use the VPN, with all others going direct.
• Excluding IPs/Domains: Define specific IP addresses or domain names that should not use the VPN.

Look for settings like "Per-App Proxy," "Rules," or "Routing" within your chosen VPN client to configure split tunneling.
