V2ray Slow Dns Server |link|

V2Ray operates by intercepting outbound traffic, routing it through predefined proxies (VMess, Shadowsocks, Trojan, etc.). Before routing can occur, the target domain name must often be resolved to an IP address. If DNS resolution is slow—whether due to high-latency upstream servers, throttling, or packet loss—the entire proxy pipeline stalls.

V2Ray handles DNS primarily over UDP. However, unstable networks or firewall interference can cause UDP packets to be lost. When this happens, V2Ray or the underlying system falls back to TCP DNS, which is intrinsically slower and more resource-intensive due to handshakes and retransmissions. v2ray slow dns server

In traditional direct connections, DNS lag affects only the initial connection setup. In V2Ray, especially with domain-based routing and freedom outbound, DNS delays propagate through every new connection request, severely impacting user experience.
