This article addresses the problems teams face when multiple people use a VPN/proxy, such as “high node latency, inconsistent speeds, and others can use it but I can’t.” It focuses on clearly explaining how to optimize high node latency, as well as its relationship with account, device, and network environment stability. It is suitable as a reference for ordinary users of clients such as Clash, V2Ray, and sing-box.
1. First determine: is the node slow, or is the team environment unstable?
Many people immediately switch nodes when they see high latency, but team scenarios are more complex. The same subscription may perform differently across different offices, broadband connections, and devices. High latency usually comes from three types of causes: local network congestion, fluctuations in node route quality, or abnormalities in the client or account environment.
It is recommended that team members first carry out a basic test in a standardized way: connect to the same node, visit the same website, and record latency, packet loss, and page load speed. If only one device is abnormal, the issue is most likely with the local client, DNS, system proxy, or firewall; if multiple people slow down at the same time, then it is more likely to be fluctuations in the node route or outbound network.
2. Team optimization steps: troubleshoot in order
- Prioritize switching to low-latency nodes in the same region: In Clash, V2RayN, and sing-box, first use the latency test feature and choose nodes with lower and more stable latency. Do not rely on just one test result; testing continuously 2–3 times is more reliable.
- Reduce the number of people using the same node at the same time: if team members all crowd onto the same free node, queuing, lag, and increased latency are likely to occur. Different nodes can be assigned by group to avoid concentrated usage.
- Check the local network: stop downloads, cloud drive syncing, and video uploads that consume bandwidth; use a wired network or 5GHz Wi-Fi whenever possible, and avoid interference from public Wi-Fi.
- Standardize client versions: if some people on the team are using very old Clash, V2RayN, or sing-box configurations, issues such as rule incompatibility, DNS leaks, or routing abnormalities may occur. It is recommended to update to stable versions consistently.
- Refresh the subscription and re-import it: after a subscription update, old nodes may have become invalid or their routes may have changed. Go to subscription management in the client, click update subscription, and then test the nodes again.
3. Why account environment stability affects latency
Here, “account environment” does not refer to a self-hosted server account, but rather to the devices, client configuration, subscription source, and usage habits involved in team use. If the same subscription is frequently switched across a large number of devices or too many nodes are connected to at the same time, it may lead to unstable connections, authentication failures, or frequent reconnections. The visible result is increased latency and webpages taking forever to open.
When used by a team, it is recommended to establish a few simple rules: each person should stick to 1–2 regular clients and avoid frequent uninstalling and reinstalling; do not repeatedly import multiple subscriptions from unknown sources; when a node fails, update the subscription first, then switch to a backup node. The free nodes provided by this site can be used for temporary testing and backup, but free resources are more affected by network fluctuations, so teams should prepare multiple interchangeable nodes for office work.
4. Common connection settings also affect the experience
- DNS: if webpage resolution is slow, enable remote DNS in the client or use the DNS settings recommended by the client to avoid pollution from the local ISP’s DNS.
- Rule mode: for daily use, it is recommended to choose rule mode so that only websites requiring a proxy go through the node, reducing unnecessary traffic.
- Global mode: enable it only briefly during testing to determine whether the issue lies in the traffic-splitting rules; long-term global mode is not recommended.
- Latency is not the same as actual speed: a low-latency node is not necessarily the fastest for downloads; packet loss, bandwidth, and the route to the target website also matter in the end.
5. Quick conclusion
When a team encounters high node latency, do not simply have everyone switch nodes at once. The correct approach is to first confirm whether everyone is affected, then spread usage across different nodes, update subscriptions, standardize clients, and check the local network and DNS. Keeping the account environment and client configuration stable can significantly reduce problems such as frequent reconnections, authentication failures, and latency spikes.
