V2ray Slow Dns Server -
geosite:cn alone contains over 80,000 domains. Loading this into memory takes CPU cycles.
Make sure your routing rules send traffic from your DNS upstream IPs back through the proxy.
Ensure that your local DNS server traffic bypasses the proxy entirely. If local DNS queries are accidentally sent through your proxy node, it creates an infinite routing loop that destroys performance.
In a typical V2Ray setup, every website you visit requires a Domain Name System (DNS) lookup to translate a human-friendly name (like google.com ) into an IP address. If this lookup is slow, your entire connection suffers, regardless of how fast your V2Ray server is. v2ray slow dns server
If the firewall allows, try switching from slowdns to ws+tls (Websocket + TLS) for faster speeds jagu. Conclusion
Here's a quick summary of common DNS issues and their primary causes: | Issue | Potential Cause | | :--- | :--- | | Slow domain resolution | Inefficient DNS servers | | DNS leaks | Using redir-host mode | | Resolution failures | Local DNS hijacking or deadlocks |
The authoritative nameserver (NS) used for the tunnel is slow to resolve. geosite:cn alone contains over 80,000 domains
the V2Ray config link, the Name Server (NS), and the Public Key provided after account creation. 2. Configure the VPN App (e.g., HTTP Custom)
V2Ray caches by default but you can adjust TTL:
"type": "field", "ip": ["1.1.1.1", "8.8.8.8"], "outboundTag": "direct" Ensure that your local DNS server traffic bypasses
Before jumping into fixes, you need to understand how V2Ray processes DNS. V2Ray can handle DNS resolution in three primary modes:
Ensure that "sniffing" is enabled in your inbound settings. This allows V2Ray to inspect the traffic, look at the target domain name, and override incorrect IP routing decisions instantly.
