树莓派4 官方系统32位 未有代理连接时，树莓派4客户端 cpu 一直在30%

ssrlive commented 3 years ago

没有测试环境，你能否帮助查看一下各线程的调用栈，看是哪里在空转？

ygao9999 commented 3 years ago

不知如何操作，给出指令，我可以试一下。

ygao9999 commented 3 years ago

在https://gitter.im/ShadowsocksR-Live/Lobby 联系你，可好？

ssrlive commented 3 years ago

哪里联系都一样。就是用 gdb 命令将软件加载进调试器，运行过程中停下来，看看每个线程的调用栈。这要会 gdb 调试器基本操作。 gdb 启动命令如下格式

gdb --args /usr/bin/ssr-client -c /etc/ssr-native/config.json

许久没用 gdb，基本命令我都忘了，你找个教程看看吧。然后再报告。

卧槽！难道是 libuv 的问题？ “树莓派4 官方系统32位” 是哪个 Linux 发行版？

ygao9999 commented 3 years ago

树莓派4 官方系统32位

Raspbian

ssrlive commented 3 years ago

我这里在Windows下工作时占13%CPU，你观察多点时间看情况啥样。

ygao9999 commented 3 years ago

杀掉ssr cpu是1， 运行ssr－client是30%，工作时31%，没有明显变化。

ssrlive commented 3 years ago

我也没头绪了，我去看看 libuv 社区……

ssrlive commented 3 years ago

找到原因了。稍后修复。

ssrlive commented 3 years ago

搞完。你测试一把？

ygao9999 commented 3 years ago

牛逼了，问题解决。
