You will need to confirm the non-VPN download and upload speeds on both the client and server sides to know what should be expected. And are you running on top of any other VPNs? And what ISP(s) is being used? Any additional hardware being used or just a software Wireguard client?

Well now that makes a lot more sense. The GFW is very likely throttling your VPN traffic. You're lucky you're getting speeds that fast. You can always try installing Shadowsocks to obfuscate your Wireguard packets. That might help a little.

no that not the issue, if that is the issue, not have very fast speed other vpn providers wireguard protocols, i also have astrill, i can connect without any problem wireguard protocols and speed is more than 200mbit, i try to solve this problem so i can use my server and not need any other vpn providers future
