This article addresses the common problems teams face when multiple people use a VPN or proxy service: high node latency, speeds that fluctuate, and one person being able to use a node while another experiences lag. It focuses on how to optimize high node latency and explains how latency relates to account usage, client configuration, and the stability of your network connection.
1. First, determine whether the problem is with the node or the team’s environment
High latency doesn’t necessarily mean the node itself is poor. When a team is using the service, common causes of inconsistent performance include sharing a subscription, using networks in different regions, and running different client versions. Start with a simple comparison test: at the same time, have 2–3 team members test latency and loading speed using the same node and target website. If everyone sees high latency, suspect node congestion or an unsuitable route. If only certain people are affected, the cause is more likely to be their local network, DNS, client, or system proxy settings.
2. Optimization steps for teams
- Prioritize nodes that are both low-latency and stable: Don’t choose based only on the lowest speed-test result. Test several times and pick a node with minimal fluctuation. We also recommend testing the free nodes on this site before importing them, rather than selecting them all blindly.
- Assign nodes by region: If team members are in different cities or use different carriers, don’t require everyone to use the same node. China Telecom, China Unicom, and China Mobile may perform differently when connecting to the same node.
- Reduce conflicts from simultaneous connections: If multiple people frequently switch nodes on a shared subscription account, connections may become unstable or drop often. Set a few preferred nodes and avoid unnecessary refreshes and repeated speed tests.
- Standardize client versions: Differences between versions of clients such as Clash, sing-box, V2RayN, and Shadowrocket can affect rule parsing and protocol compatibility. Where possible, standardize the versions and import procedures recommended to the team.
- Check proxy rules: If latency increases noticeably with global proxy enabled, switch to rule mode. If rules appear to be matching incorrectly, temporarily switch to global mode to check whether the rules are causing traffic to take a longer route.
3. Why account environment stability affects latency
The “account environment” is one of the easiest things to overlook when a team uses a shared setup. This doesn’t mean the account itself somehow accelerates connections. Rather, using the same subscription across multiple devices, networks, and clients at the same time makes connection states more complex. For example, some people may switch nodes frequently, others may leave downloads running, and someone else may have a misconfigured client that keeps reconnecting. Together, these issues can make it seem as though the “node latency is high.”
Set a few basic guidelines for the team: keep 2–3 backup nodes, avoid having everyone crowd onto the same route, don’t refresh the subscription too frequently, and don’t share subscription links outside the group. If a subscription link is exposed and used by unknown devices, it can also lead to connection issues, rate limiting, or unpredictable latency spikes.
4. Client and local network troubleshooting checklist
- Restart the client and confirm that the system proxy is enabled correctly.
- Test using Wi-Fi and a mobile hotspot to rule out problems with your local broadband connection.
- Close other proxies, accelerators, and packet-capture tools to avoid port conflicts.
- Update the subscription and run another speed test. Don’t use nodes that have expired or timed out.
- If you suspect DNS issues, try changing the client’s built-in DNS or switching to rule mode.
If you’re using a Clash-based client, first test the nodes on the “Proxies” page, then visit commonly used websites to check real-world performance. If you’re using V2RayN, check the logs for errors such as timeout, connection reset, or TLS handshake failed. A large number of timeouts usually indicate a problem with route quality, the local network, or configuration compatibility.
5. Recommended practices for teams
Team administrators can put together a simple guide covering client download links, subscription import instructions, recommended node naming conventions, and how to report problems. When reporting an issue, members should include at least the client name, network they’re using, node, and a screenshot of any error. This makes it much easier to diagnose than simply saying “it’s really slow.” In short, optimizing high latency isn’t just about changing nodes; it requires adjusting node selection, account usage habits, client configuration, and the local network together.
