How well does your computer run applications under 100% load?
For example if you were to encode a video with x264, or compile a large C program, you should be using 100% of your processor on all cores.
Can you smoothly move around windows on your desktop like that? Can you run games or OpenGL programs smoothly? The Linux kernel has a lot of options related to this and I've been changing options in the kernel for years looking for the best config.

Well before you waste years experimenting with stupid shit you should educate yourself on the basics, because encoding videos and compiling stuff are tasks that don't even grow properly horizontally. You don't get to use 100% of all your cores by doing that stuff.

For me everything starts to lag when CPU's at 100%. I also get freezes when my RAM fills up and swap is being tried to be used.
Anyone got any solution for that? Arch here.

Changing config options in the kernel isn't stupid shit.

htop shows constant 100% cpu usage on all cores when compiling with GCC, or encoding with x264.

This kind of situation (100% to some extent) is something I have problems with as well. Instead of tweaking kernel configs I've just run programs like cpufreq or cpulimit (protip: set a manual fan speed) or tried to make use of cgroups where I can. My limits tend to be network/IO more than RAM or CPU on most of my computers, though. Any tips?
