In order to understand “segmentation fault,” it is a must to know the basic idea of segmentation and its implementation in C programming. When we need to execute any program, it should be loaded into memory first. Paging This was designed to allow non-contiguous space allocation to processes.

Non-functional testing examines how a system operates rather than looking at specific functions or behaviors. To reach better test coverage for a product, we should examine the whole system. Data from non-functional tests can define optimal to stressful loads on a system.

Because microprocessors are so fast, computer architecture design has evolved towards adding various levels of caching between compute units and the main memory, in order to hide the latency of bringing the bits to the brains. We formulate the problem as a Mixed Integer Program (MIP). can we actually make this work in practice?

The fact that this shows up as CPU time suggests that the reads were all hitting in the system cache and the CPU time was the kernel overhead (note ntoskrnl.exe on the first sampled call stack) of grabbing data from the cache.

First, a bit of operating-system design context. It is desirable for a program to be able to go to sleep and then wake up a little while later. 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?
