systemd-analyze may be used to determine system boot-up performance statistics and retrieve other state and tracing information from the system and service manager. systemd tracks processes using the Linux kernel’scgroups subsysteminstead of using process identifiers (PIDs); thus, daemons ca...

通过使用Boot Loader Interface接口,systemd-boot 可以向systemd-analyze(1)提供 UEFI 固件启动所花费的时间。 键绑定 在启动菜单中可以使用下列按键 ↑(Up),↓(Down),j,k,PageUp,PageDown,Home,End 在启动项之间上下移动 ↵(Enter) 启动选中的项
Boot it, log into it and run systemd-analyze, observe the output then reboot, log into again and observer the output again. Repeat the above steps ( reboot,login,run systemd-analyze ) to always see an incremental increase in the time it took to boot which in turn is in no relation wit...
systemd 是一个 Linux 系统基础组件的集合,提供了一个系统和服务管理器,运行为 PID 1 并负责启动其它程序。功能包括: 支持并行化任务; 同时采用 socket 式与 D-Bus 总线式激活服务; 按需启动守护进程(daemon); 利用Linux 的 cgroups 监视进程;比如systemctl 显示 CPU 和 Mem 信息就是基于此哦。
