Good day,
is there any chance to limit the cpu core usage to 2 core? 1 user use the all 4 core, when I upgraded the VPS to 12 core, all eated... No cgroups on aaPanel. Can limit the core or MHz for 1 website??


You can specify a number to Web Admin > Server Configuration > General > CPU Affinity, this is for the whole server, can not specify to website.
