This article addresses common issues teams encounter when multiple people use a VPN or proxy service: “high node latency, speeds that fluctuate, and the same subscription working for some people but lagging for others.” It explains how to optimize high node latency and how latency relates to account environment, client configuration, and network egress stability.
1. First, determine whether the node is actually slow or your local environment is unstable
Many teams see 300 ms or 800 ms in their client and immediately assume the node is the problem. In reality, high latency can have three causes: congestion on the local broadband connection or office Wi-Fi, incorrect client routing rules, or unstable connections caused by multiple people frequently switching between nodes on the same account or subscription. Have team members compare results using the same client and subscription during the same time period, rather than relying on one person’s experience alone.
- Refresh the subscription in clients such as Clash, V2RayN, and sing-box, and confirm that everyone has the same node list.
- Select the same node and compare the “latency test” results with the actual experience of loading websites and videos.
- Try a mobile hotspot or a different broadband connection to rule out office network throttling, DNS poisoning, or circuitous routing.
- Disable other proxies, accelerators, and browser extensions to avoid stacking multiple proxy layers.
2. Optimization priorities for team use
The factor teams most often overlook is their usage habits. Frequent speed tests, switching nodes in bulk, and prolonged heavy downloads can all degrade connection quality. Optimize in the following order:
- Set preferred nodes: Don’t have everyone use the same lowest-latency node. Assign different nodes by region or purpose—for example, separate nodes for office work, research, and video calls.
- Run fewer speed tests: Batch testing in a client opens a large number of connections at once. When several team members do this at the same time, it can cause brief periods of lag.
- Use rule-based mode: In Clash or sing-box, use rules or automatic routing to let domestic websites connect directly and avoid unnecessary proxy traffic.
- Update subscriptions regularly: Free nodes can change quickly. For the free nodes provided on this site, follow the instructions on the page to import the latest subscription promptly instead of relying on an outdated configuration.
3. Why account environment stability can affect latency
Here, “account environment” doesn’t mean modifying the server side. It refers to how team members use the client when sharing a subscription or account. When multiple people connect at once from different cities, carriers, and devices, performance can vary. Excessively frequent logins, leaked subscription links, or too many devices can also lead to connection resets, spikes in latency, or unavailable nodes.
We recommend that the team lead manage subscription links centrally and avoid leaving them publicly visible in group chats. Replace subscriptions promptly when someone leaves or changes devices, and ask team members not to import the same subscription onto too many devices they rarely use. This isn’t about “magic” speed boosts; it’s about reducing abnormal connections and unnecessary usage so nodes remain more stable.
4. Recommended client settings
If you use Clash Verge, Clash Meta, V2RayN, or sing-box, start by checking these settings: choose rule-based mode; use the client’s recommended DNS configuration rather than mixing several public DNS services; after enabling the system proxy, make sure your browser isn’t using another proxy as well; and ensure that protocols such as VLESS, VMess, Trojan, and Shadowsocks aren’t imported with incorrect fields. When latency is high, don’t focus only on the test results—pay attention to whether websites load instantly, videos buffer, or chat apps disconnect.
In short, the key to optimizing node latency is to rule out local network issues first, standardize team usage, and then update subscriptions and routing rules. If a node continues to show high latency for multiple people across different networks, switch to another one instead of repeatedly tweaking it.
