Daily maintenance of Windows XP is a time-consuming and boring task. If Windows XP is smarter, it would be nice to perform automatic maintenance. Next, we will introduce you to the technique of enabling Windows XP to perform automatic maintenance through the. inf file. The specific content of automatic maintenance can be set at will, but it needs commands. For example, Xcopy is used for file backup, Defrag is used for disk fragmentation, and Del is us

You can use the task plan or the at. EXE command to complete the fragmentation in the task plan. Next, I will take the C drive as an example at a.m.. The specific operation steps are as follows:1. Open notepadProgram, Input: defrag.exe C:-v-F> C: \ Defrag-D.LOGExplanation: Use the defrag.exe command to sort out the C drive, output detailed results, and save the results to the C: \ Defrag-D.LOG in redirectio

. Hidden parameters for Windows XP disk grooming Windows XP Disk Defragmenter Defrag.exe has a hidden parameter that is not even described in the XP Help file, which is-B, after using it, the Defrag tool will optimize the system's startup files and applications (XP can track how often the application is used to adjust its location on the disk) , so as to achieve the purpose of system optimization. You can enter in the command line prompt window:

After installing the CPU, the next step is to start installing the memory strips. Before installing the memory strips, you can check the motherboard specification for the type of memory that the motherboard can support, the slot data that can be installed on the memory, the maximum supported capacity, and so on. Although these are simple, do you know how different memory strips are differentiated? Do you know why EDO RAM memory must be in pairs to be

CentOS7 Disable Transparent Huge Pages Transparent Huge Pages (THP) has been introduced since the CENTOS6 version, and this feature is enabled by default, starting with the CentOS7 version. Although THP is intended to improve memory performance, some database vendors recommend shutting down THP (such as Oracle, MARIADB, MONGODB, etc.) directly, which may cause performance degradation. First check the enabled status of the THP: [Root@localhost ~]# Cat/sys/kernel/mm/transparent_hugepage/

the GUID is the identifier for the power management scheme and we can execute the command "powercfg-list" to get it. As shown in Figure 1, if we want to remove the Power management scheme named JP, execute the command "Powercfg-delete 53d4577a-49c1-4867-ba59-7fd20316fa2d".

 1, the address space of the processIn a 32-bit operating system, the process has an address space of 0 to 4GB,As follows:Figure 1Here are the main instructions for stack and heap:Stack space (stack and stack) is controlled by the operating system, which mainly stores function addresses, function parameters, local variables, and so on, so the stack space does not need to be large, typically a few megabytes in size.The use of the heap space is controlled by the programmer, who can manipulate th

start the Linux kernel. 2.1 concepts and functions of bootloader Bootloader is the boot loader of an embedded system. It is the first program that runs after the system is powered on. It acts like the BIOS on a PC. After the system initialization task is completed, it will copy the Linux kernel in non-volatile memory (usually flash or Doc) to ram, then, the system jumps to the First Command of the kernel to start the Linux kernel. It can be seen that

Today, Dwight Silverman will give you a little knowledge. When we buy a computer, do we choose 32-bit Vista or try 64-bit vista? Before you answer this question, take a look at this knowledge first. The 64-bit version can effectively utilize more memory than the 4G-limited 32-bit Vista. As you can see from this sentence, 4 G is a watershed. Less than 4G of memory, 32-bit Vista is not mistaken, but more than 4G, you need 64-bit vista to take full advantage of such a large amount of memory. Peopl

do you manage the storage operationally? How to manage storage operations? Off compute node storage-Shared File System Extends operators use separate compute and storage hosts. compute services and storage services have different requirements, compute hosts typically require more CPU and ram than storage hosts. therefore, for a fixed budget, it makes sense to have different deployments for your compute nodes and your storage nodes with comp

If you had asked me what virtual memory was severalYears ago, I 'd have given you some hand-wave explanation about makingIt appear as if your computerHas much more RAM than it actually does. Which is only sort of correctAnd fairly imprecise. Sometimes people will get stuck on the ideaWriting dataTo the file system, which is not quite correct either.

in the opened table (open tables), plus some additional overhead.MySQL 5.5 (and version 5.1 with plug-ins) allows you to specify a block size of 8 KB or 4 KB. MySQL 5.5 can have multiple buffer pools, because each cache pool has one mutex, so setting up multiple pools can alleviate some mutex bottlenecks.More InnoDB tuning informationanother way to calculate cache size Set the primary cache to the minimum value; This can be specified if there are many other applications running on the same mach
