Ensure your browser or system has caching enabled to prevent repeated slow lookups. 2. Configure V2Ray dns Object
When accessing domestic websites (websites within your country), sending DNS queries through the proxy adds unnecessary latency. V2Ray supports a special "local" mode for DNS over HTTPS that bypasses the routing subsystem entirely.
If you'd like, I can provide a more in-depth guide on how to configure your or walk you through setting up your own specialized Slow DNS resolver .

Standard DNS uses UDP. If V2Ray forces UDP traffic to wrap inside a heavy TCP proxy connection, resolution speeds plummet. Step 1: Diagnose the DNS Bottleneck
If you must use TUN mode, you need explicit routing rules to exempt DNS traffic from being captured. Add rules that send DNS queries directly rather than through the proxy tunnel:
V2Fly's official documentation explicitly notes that . Using TCP-based DNS (as opposed to the standard UDP-based DNS) introduces additional connection setup overhead that can degrade performance, especially for high volumes of queries. Ensure your browser or system has caching enabled
If you're using GUI clients like v2rayA or v2rayNG, check for DNS optimization features built into the client. v2rayA offers five anti-pollution modes, including DNS Forward (queries through proxy) and DoH (DNS over HTTPS) options. Earlier versions had known issues with all-DoH configurations causing slow lookups, but these have since been fixed.
If your connection still feels sluggish, apply these advanced infrastructure tweaks:
In conclusion, V2Ray slow DNS server issues can be frustrating and impact online experiences. By understanding the causes and consequences of slow DNS server issues, users can take practical steps to resolve them. By using fast and reliable DNS servers, configuring V2Ray settings, and leveraging DNS proxies, users can improve DNS resolution speeds and reliability. As the popularity of V2Ray continues to grow, it is essential to address these issues to ensure a seamless and efficient online experience. V2Ray supports a special "local" mode for DNS

Most users implement this using mobile apps like , v2rayNG , or ZiVPN . 1. Generate Your Server Credentials
If your V2Ray connection feels unusually slow even for a DNS tunnel, check these configuration points:
