When running a single user thread, you will often get the advertised single-core Turbo frequency, but if the operating system enables more cores to handle (even very short-lived) background processes, your frequency may drop unexpectedly. For simple loops, you can look at the assembly code and count instructions.

When a project’s source code is available to all, the question of security isn’t far behind. How can something be secure if anyone can examine the code and look for security flaws? Would-be attackers can comb through source code to find security flaws. Let’s start with the big one, security. Sometimes they do!

First, a bit of operating-system design context. Ideally the CPU goes to sleep when Sleep(1) is called, in order to save power, so how does the operating system (OS) wake your thread if the CPU is sleeping? If multiple threads can synchronize or coalesce their timer waits then the system becomes more power efficient.

From operating systems to versions to hardware specs, mobile devices stand unique even after being billions in number. As a result, we can relate the test automation to a machine that needs servicing regularly with regular checks and regular updates into the system. This challenge is the easiest to tackle among all the others.
