Because most of the online Chinese description bootchart tools are outdated, so there is also the production of this diary. Bootchart is a handy tool for analyzing Linux startup processes, the results of this tool can be used as a reference for optimizing the startup speed, after the package is installed directly in a newer release, the chart that records the time it takes to start each component at system

Most server administrators know that the MySQL database management system (RDBMS) is a highly flexible software block with a wide range of startup options that can be used to modify related behavior. However, most people are not aware that standard MySQL clients have an equal amount of startup options, some of which are extremely useful in day-to-day MySQL interactions. These options are not "secret" in the

Linux Startup time limit Optimization-Linux general technology-Linux programming and kernel information. The following is a detailed description. After the Linux cutting of the embedded application was completed last time, it still took about 7 s to start Linux. Although barely acceptable, it still did not reach my goal-within 2 s. Moreover, in the actual commercial environment, the requirement for device reliability is "5 9" (99.999%, that is, the OO

After the Linux cutting of the embedded application was completed last time, it still took about 7 s to start Linux. Although barely acceptable, it still did not reach my goal-within 2 s. Moreover, in the actual commercial environment, the requirement for device reliability is "5 9" (99.999%, that is, the OOS time is less than 5 minutes/year ), this means that the Linux Startup (device reset) time is reduced every second, which significantly improves

1. Linux kernel Startup Process OverviewAn embedded Linux system can be divided into four parts: Boot Loader, Linux kernel, file system, and application. Bootloader is the first code executed after the system is started or reset. It is mainly used to initialize the processor and peripherals and then call the Linux kernel. After completing system initialization, the Linux kernel needs to mount a file system as the root file system ). The root file syst
