Anonymous users2024-02-06Traditionally, different Linux distributions and different kernels have made changes to various parameters and settings to make the system get better performance. The following four sections describe how to optimize performance in Red Hat Enterprise Linux AS and SUSE Linux Enterprise Server with the following tips:
1. Disabling Daemons
2. Shutting down the GUI
3. Changing kernel parameters
4. kernel parameters
5. Tuning the Processor Subsystem
6. Tuning the memory subsystem
7. Tuning the file system (file system subsystem tuning).
8. Tuning the network subsystem

Anonymous users2024-02-05Summary of Embedded Linux Boot Time Optimization:
1. Replace zimage with image, zimage is a compressed kernel image file, so using image saves the time spent on decompression during loading (about 2 3 seconds of startup time). However, if you use Image, you should consider whether the space of Nandflash is sufficient.
2. There are three kinds of file system images: ramdisk, jffs2 and cramfs, and the kernel loads these three images at the fastest rate cramfs, followed by jffs2, and finally ramdisk. CRAMFS is a read-only file system. Usually a product is a combination of all three.
3. Optimize the bootloader to reduce its running time.
4. Reduce the size of the kernel, for example, leave the driver modules that must not be loaded in the boot stage behind the file system to load, so as to reduce the running and loading time of the kernel.
5. Optimize or turn off the debugging serial port output.
6. Load the driver behind the file system, display the application interface first, and then load the necessary driver modules in the background.
7. Save the entire system operating environment to RAM, power-on is just a system recovery process.
8. Carefully optimize the kernel and each driver module to debug the delay of each part to the fastest.
9. Optimization of the application to reduce the startup time of the application.

Lu Rui, hello, I know you. Dr. Zhang was still talking a few days ago that you should come to the hospital according to the course of treatment, to be honest, it is still difficult to avoid allergens, and people with allergies may be allergic to many things.
