Performance tuning is the improvement of system performance. Typically in computer systems, the motivation for such activity is called a performance problem, which can be either real or anticipated. Most systems will respond to increased load with some degree of decreasing performance.
In the 2.6-series of the Linux Kernel, the LVM is implemented in terms of the device mapper, a simple block-level scheme for creating virtual block devices and mapping their contents onto other block devices. This minimizes the amount of relatively hard-to-debug kernel code needed to implement the LVM.

Location of the "O(1) scheduler" (a process scheduler) in a simplified structure of the Linux kernel. An O(1) scheduler (pronounced "O of 1 scheduler", "Big O of 1 scheduler", or "constant time scheduler") is a kernel scheduling design that can schedule processes within a constant amount of time, regardless of how many processes are running on the operating system.
The β service level is a quantity-oriented performance measure describing the proportion of total demand within a reference period which is delivered without delay from stock on hand: β = 1 − E x p e c t e d b a c k o r d e r s p e r t i m e p e r i o d E x p e c t e d p e r i o d d e m a n d {\displaystyle \beta =1-{\frac {Expected ...
The optimum quantity is the same as the optimum quantity in the first diagram. If the firm is a monopolist , the marginal revenue curve would have a negative slope as shown in the next graph, because it would be based on the downward-sloping market demand curve.
Linux adoption is the adoption of Linux-based computer operating systems (OSes) by households, nonprofit organizations, businesses, and governments.. Android, which runs on Linux, is the world's most widely used computer operating system.
