aside from the new logo, other work building up for the eventual systemd 244 release includes cpuset cgroups v2 controller support to restrict processes to specific cpus with the new allowedcpus= setting, the signal for restart jobs is now configurable, support for systemd to read configuration options from the efi "systemdoptions" variable, udev … 第四單元：StarUml檔案決議本單元采用了圖模型決議UML。.

MySQL considers all 6 cores at its disposal and since they appear to be underutilized (16%. utime_pct + stime_pct is 16.4% which is simply 98.5/6. 다른 버젼을 사용해도 되지만, 서버용으로 GUI 없이 사용하기 위해서는 Lite 버젼이면 충분합니다.Lets interpet these numbers: mysqld sees 6 CPUs which is how many we have specified with AllowedCPUs=0,1,2,3,4,5 utime_abs + stime_abs (sum of the user and system CPU time) is 98.5% which is in line with what top reports.
