路由和server用okhttp通信，在并发较高的情况下会出现请求等待吧，okhttp最大请求才64

这里的路由和server通信是否可以用一个长连接来维护更好

The issue only identifies router-to-server communication through OkHttp and reports waiting under high concurrency because of a 64-request limit. Start by locating that communication path and its concurrency configuration; determine whether a long-lived connection is feasible and define how completion would be measured under concurrent requests. No files or tests are named, so the scope needs clarification before implementation.
