I find this a highly interesting problem. How do you measure how much CPU time a program needs? The OS has ceded its control of the CPU to the program. Does it just look at the clock after it’s in charge again to derive a program’s load?

While we’re at it: How does the OS even yank the CPU away from the currently running process?

Google chrome only needs 10% memory? My guy has that 2 TB RAM server (or renamed firefox to google-chrome)
