V2ray Slow Dns Server [verified] -

Slow DNS servers are a hidden but severe performance killer in V2Ray deployments. They increase latency, cause timeouts, and degrade user experience disproportionately relative to proxy bandwidth. By implementing local caching DNS, using fakedns , or switching to low-latency upstream resolvers, users can eliminate this bottleneck. For high-performance proxy servers, DNS resolution latency should be monitored as a first-class metric alongside throughput and encryption overhead.
