Linux has a number of excellent tools to help us analyze the performance metrics of the server and assist in the development of debugging work. The following lists only the underlying commands and are generally integrated into a Linux environment without having to be installed again.

() can be any combination of MCL_CURRENT and MCL_FUTURE, they represent "Keep allocated address space resident physical memory" and "keep future allocated address space resident physical memory ". For Linux, this is very domineering for functions. Only the root user has the permission to call them. 2. shmget () and shmat ()This function can apply to the operating system for Large Page memory (Large Page ). The large page memory features pre-allocated

memory and swap are functionally identical, except for the difference in performance between physical storage components (memory and disk). The operating system will swap in and out according to the characteristics of the program using memory, leaving the physical memory as much as possible to the program that needs it most. However, this scheduling is based on a predetermined set of rules, and does not fully meet the needs of the program. Some speci

Why do you want performance tuning? Most Linux distributions are designed to be fully compatible with most computers in the marketplace. This is a fairly mixed set of hardware (hard drive, video card, NIC, etc.). So Red Hat, Suse,mandriva and some other distribution vendors have chosen some conservative settings to make sure the installation is successful.Simply put: Your distribution is running well, but

A disk is usually the slowest subsystem of a computer, and it is also the most prone to performance bottlenecks, because the disk is the farthest from the CPU and the CPU access to the disk involves mechanical operations, such as rotating shafts and track searching. The speed difference between hard disk access and memory access is calculated by an order of magnitude, just like A disk is usually the slowest subsystem of a computer, and it is also the
