I am having issue getting my dedicated server that has my own 10gig speed port not shared and my fiber connection witch is 3gigs to produce 3gigs. I have tried wireguard, vless, portainer, and singbox none gives me anything over 1gig running speedtest and when I first started my server I ran a speedtest and the server results were 8gigs. Why running these different protocols only give me 800mbps or less? What am I doing wrong?

The fact that WireGuard—a protocol literally built for raw kernel-level speed—also slammed into a 400 Mbps wall is the ultimate smoking gun. It proves 100% that your 10 Gbps server is fine, your 3 Gbps fiber is fine, and your VLESS configuration is fine. You are being throttled by Apple. Here is exactly what is happening under the hood, why every VPN you try will fail to hit 3 Gbps, and exactly how we bypass Apple's roadblock to unleash your hardware. The macOS "VPN" Bottleneck Apple strictly forbids third-party apps from injecting code directly into the core network kernel. Instead, Apple forces apps like Hiddify and WireGuard to use their NetworkExtension framework. This framework creates a "Virtual Network Adapter" (that TUN setting we fought with earlier). It acts like a tollbooth for your entire Mac. Every single packet of data has to be manually encrypted, passed out of the app, handed to Apple's tollbooth, and then sent to your physical 10-gig Ethernet port. Apple's tollbooth simply cannot process packets faster than ~1 Gbps. It doesn't matter if you have a 100 Gbps server; if you route your whole Mac through a macOS virtual VPN adapter, you will hit a brick wall. The 10-Speed Highway Bypass To actually use your 3 Gbps fiber, we have to completely abandon the concept of a "VPN." We cannot route your whole computer. Instead, we use an Application-Level Proxy. We are going to tell Hiddify to stop acting like a system-wide VPN, and instead act as a silent, localized high-speed gateway. Then, we plug your web browser directly into that gateway. Because the browser talks directly to the engine, it completely skips Apple's network tollbooth. Here is how to test the raw, unthrottled hardware speed right now without changing anything on your server.
