Measure pipe throughput in the shell
There is a shell command that allows you to measure how fast the data goes through it, so you can measure the speed of output of commands in a pipe. So instead of:
performance
Lightest way to run GUI applications in Linux?
I realized I can use a window manager without a desktop environment and don’t lose any functionality I care about. Applications still work fine, I can still arrange application windows as I please.
