Quick answer快速结论
If Just My Socks feels slow in China, do not upgrade the plan first. Compare regions, refresh the client profile, check rule mode and test the same target service on the same network before changing anything.如果 Just My Socks 在中国大陆变慢，不要第一反应就升级套餐。先比较不同地区节点，刷新客户端订阅，检查规则模式，并在同一网络下测试同一个目标服务。

Practical troubleshooting checklist具体排查清单
Use this checklist before changing plans: test another node, switch client app once, try wired or another Wi-Fi, compare the target app with a normal website, check whether only evening hours are bad, and then inspect HK, LA or Tokyo in that order based on the failed scenario.换套餐前先按这个顺序排查：试另一个节点、只换一次客户端、换有线或另一个 Wi-Fi、把目标应用和普通网站对比、看是不是只有晚间变差，最后再按失败场景去看 HK、LA 或 Tokyo。
If only AI tools are slow, compare LA. If nearby pages or Asia services feel slow, compare HK or Tokyo before assuming the whole service is unusable.如果只有 AI 工具慢，先比较 LA；如果附近网页或亚洲服务慢，先比较 HK 或 Tokyo，不要直接判断整个服务不可用。
Quick diagnosis快速判断问题
Pick the symptom closest to what you see. The goal is to separate routing, client and local-network problems before buying another package.先点最接近的症状。目标是在买另一个套餐前，把路由、客户端和本地网络问题分开。
Not opening打不开
If nothing opens, test client DNS, system proxy mode and whether the subscription is actually loaded before changing plans.如果完全打不开，先查客户端 DNS、系统代理模式，以及订阅是否真的导入成功，再考虑换套餐。
Slow speed速度慢
If pages open but feel slow, compare HK and LA on the same network, then test local Wi-Fi before upgrading the package.如果能打开但慢，先在同一网络比较 HK 和 LA，再检查本地 Wi-Fi，最后才考虑升级套餐。
AI unstableAI 不稳定
If only AI tools are unstable, compare LA first because the target services and account environment often matter more than map distance.如果只有 AI 工具不稳定，先比较 LA；目标服务和账号环境往往比地图距离更关键。
Few nodes节点少
If the client shows fewer nodes than expected, refresh the subscription and check the service detail page. Buying another plan should be the last step.如果客户端节点少，先刷新订阅并核对服务详情页。不要一上来就买另一个套餐。
Clash failedClash 连接失败
If Clash fails to connect, treat it as a client problem first: profile format, rule mode, DNS and selected node.如果 Clash 连接失败，先按客户端问题处理：配置格式、规则模式、DNS 和已选择节点。

Possible causes, ordered by probability可能原因：按概率排序
Most slow reports fall into five buckets, roughly in this order: ISP routing, node selection, client configuration, local network and plan limitation.大多数慢速问题可以按概率分成五类：运营商路由、节点选择、客户端配置、本地网络、套餐限制。
Do not start from plan limitation. First test another node, another client mode and another network. If the same symptom stays, then compare another package or route.不要一开始就归因到套餐限制。先试另一个节点、另一个客户端模式、另一个网络；如果症状仍一致，再比较其他套餐或路线。
1. ISP routing and 2. node selection1. 运营商路由与 2. 节点选择
Start with ISP routing because Telecom, Unicom and Mobile use different international paths; compare the same task on LA and HK.先查运营商路由，因为电信、联通、移动使用不同国际出口；用同一任务比较 LA 和 HK。
Node selection is next. LA, HK and Tokyo solve different jobs: US-facing apps, China-side browsing and Japan or Asia paths should not be tested as one single problem.第二看节点选择。LA、HK、Tokyo 对应不同任务：美国方向应用、中国侧浏览、日本或亚洲路径，不应混成一个问题。
3. Client configuration and 4. local network3. 客户端配置与 4. 本地网络
Client configuration is the third suspect. In Clash, check that the profile imported correctly, a node is selected, rule mode covers the app, and DNS is not leaking to the wrong resolver.第三看客户端配置。Clash 里要确认配置导入成功、已选中节点、规则模式覆盖目标应用、DNS 没有走错解析。
Local network is fourth. Test another Wi-Fi or wired connection, restart the client once, and compare one normal website with the failing app.第四看本地网络。换一个 Wi-Fi 或有线连接，只重启一次客户端，并把普通网站和出问题的应用分开对比。
5. Plan limitation5. 套餐限制
Plan limitation is real, but it should be checked last. Traffic cap, device limit and the specific checkout package matter only after route and client problems are ruled out.套餐限制确实存在，但应该最后检查。流量、设备数和具体套餐，只有在线路和客户端问题排除后才更有意义。
If the current package is wrong for your use case, use the node switching guide below instead of upgrading blindly.如果当前套餐和用途不匹配，按下面的节点切换建议走，不要盲目升级。
Node switching guide: LA, HK or Tokyo节点切换指南：LA、HK 还是 Tokyo
Choose LA when the failing service is an AI tool, developer platform, US website or US-oriented account flow.AI 工具、开发者平台、美国网站或偏美国的账号流程出现问题时，选择 LA。
Try HK when ordinary China-side browsing feels slow or regional response matters. Try Tokyo when Japan or nearby Asia paths are the main target.中国侧日常浏览慢或区域响应重要时尝试 HK；日本或亚洲邻近路径是主要目标时尝试 Tokyo。
Clash troubleshooting and when to consider VPSClash 排查，以及何时考虑 VPS
If Clash is the problem, do not buy a new plan first. Check subscription URL, profile import, selected node, DNS and rule mode, then continue with the dedicated Clash guide.如果问题在 Clash，不要先买新套餐。先查订阅链接、配置导入、已选节点、DNS 和规则模式，再看专门的 Clash 指南。
Switch to VPS only when you need server control, logs or custom routing. If you only need a different managed route, compare another JMS region first.只有需要服务器控制权、日志或自定义路由时，再考虑 VPS。如果只是需要另一个托管线路，先比较 JMS 其他区域。
Once the primary route is clear, compare it against the pricing and plan table.选定主线路后，再对照价格与套餐表。

FAQ常见问题
Does slow JMS mean I bought the wrong plan?JMS 很慢是不是代表套餐买错了？
Check ISP routing, node selection, Clash configuration, local Wi-Fi and the target app in that order; change plans after completing the sequence.按运营商路由、节点选择、Clash 配置、本地 Wi-Fi 和目标应用的顺序排查；完成后再决定是否换套餐。
Which node should I try when Just My Socks is slow?Just My Socks 慢时先换哪个节点？
Use LA when AI tools or US services are the problem. Try HK when ordinary China-side browsing feels slow. Try Tokyo when Japan or nearby Asia services are the main target.AI 工具或美国服务出问题时看 LA；中国侧日常浏览慢时看 HK；日本或亚洲邻近服务是目标时看 Tokyo。
What should I check when Clash connects but nothing opens?Clash 显示连接但打不开时查什么？
Check whether the subscription imported correctly, whether a node is selected, whether rule mode sends the app through the proxy, and whether DNS is still using the wrong resolver. Then use the Clash guide.先确认订阅是否导入成功、是否选中节点、规则模式是否让目标应用走代理，以及 DNS 是否仍走错解析。然后按 Clash 指南排查。
Why is only ChatGPT or one app unstable?为什么只有 ChatGPT 或某个应用不稳定？
If one app is slow, check its account environment and rule mode. If every app is slow, check the local network, ISP route and selected node.只有一个应用慢时检查账号环境和规则模式；所有应用都慢时检查本地网络、运营商路由和所选节点。
When should I switch from JMS to VPS?什么时候该从 JMS 换成 VPS？
Consider VPS when you need root access, custom routing, protocol changes or server logs. If the real problem is only choosing a route, fix the JMS setup before rebuilding everything.需要 root 权限、自定义路由、协议修改或服务器日志时再考虑 VPS。如果问题只是选线路，先把 JMS 配置和节点排查完，不要马上重建整套。
