How to Help Your Business Become an AI Early Adopter
"Control groups are really, really great. They can effectively
make your system act as if it were two or more systems in one. It's
like virtualization without all the overhead and much more
efficient than e.g. renicing. (Just a little overhead... and no
hard cpu limit yet, but still great!)
You can lock a process into a jail that is only as fast as e.g.
10% of your cpu and has only 10 % of your memory and 10 % of your
disk speed. Pretty much whatever it does, it won't be able to
really annoy you. This means that e.g. big compiles in the
backgroud *really* don't affect your browsing *at all*.
