V2ray Slow Dns Server 🔥

The primary reason DNS causes slowness in V2Ray is the "double-hop" latency. In a typical setup, a DNS query must be sent through the proxy tunnel, resolved by a remote server, and then sent back. If the DNS server is geographically distant from the V2Ray outbound node, the round-trip time increases exponentially. Furthermore, if the V2Ray configuration forces all DNS traffic through a single, congested public resolver like 8.8.8.8 without considering the user's location, the "Time to First Byte" for every website will be noticeably high. This creates a bottleneck where the proxy is fast, but the "handshake" required to find the destination is slow.
