参考WSL 中的高级设置配置 | Microsoft Learn
查看LinuxCPU核数
cat /proc/cpuinfo | grep "processor" | wc -l先关闭所有wsl终端，远程连接开发的IDE也需要关闭，因为工具链开着给你wsl没有完全关闭，在Windows的power shell终端命令行窗口可以实验以下命令检查是否wsl已经关闭
wsl --list --running如果响应没有正在运行的分发版就说明所有Linux子系统已经关闭
创建文件C:\Users\<UserName>\.wslconfig，目录必须对，例如C:\Users\Yezi
然后文件内容复制下面信息，CPU核数为processors，修改即可，在确认所有Linux子系统已经关闭的情况下，保存文件重启wsl即可
