Smart defrag A total of two software skins for users to switch to support the use of Simplified Chinese. The software configuration option is automatically ejected after the software is installed, and the user can choose to switch freely. Smart Defrag Configuration Interface optional skin and prophecy Smart Defrag main interface design simple and ea

to do the task of planning inside. And it's free! Supports NTFS and FAT32, supports Windows xp/vista/win7 systems, and new versions support 64-bit systems. Defraggler's command-line version is too simple to use for system resources, without adding system services.I used to think I had to defragment it. The disk's free space should be much more, but I once found that there was a lot less space available after defragmenting the pieces. Later found that the software before the disk defragmentation

A disk tool designed for NT/2000/XP/Vista, Supports almost all file systems, including fat16, FAT32, NTFS, ntfs5, FS (encrypted file system) and so on, is a rare good tool. Yes The hard disk is automatically reorganized at the specified time, and long Chinese file names are supported. O O defrag Professional Edition supports the following operating systems: + Windows NT 4.0 Workstation (SP6 or above) + Windows 2000 Professional + Windows XP Ho

It is well known that the system will cause disk fragmentation after running for a while, which can seriously affect the speed of the system, so Windows system itself provides the defrag command to help users clean up disk fragmentation, Windows 7 is no exception, and Vista is different from windows The defrag in 7 adds more options, with command line versions containing more directives.

Disk defragmentation is a very useful feature, especially for long-used systems, as well as some computers that frequently delete files, and it is necessary for the system to defragment the disk at regular intervals. This allows you to sort out some of the file fragments and delete them. 1 The only way to open disk defragmentation is to: Start → All programs → accessories → system tools or right-click C-Drive, select Properties, you can see the Disk Cleanup function. 2 To add disk defragmen

Defrag: Defragmentation of disk [applicable] disk reads and writes many times, or the disk uses the time to be very long, may need to use this commandDefragment the disk. Disk fragmentation does not mean that the disk is broken, but only because of multiple copies and deletionsIn addition to files, disk usage can be very incoherent, causing slower speed.

This article describes the MySQL regular batch check table repair and optimization table optimize the shell script, for MySQL database maintenance is very useful!

type, we are accustomed to the int type of the field set length, in fact, you set not set are no egg use, The int type is a 16-bit storage space, then its storage scope has been determined, so int (1) and int (20) are the same for storage and calculation, let's change it, I just learned. 4, we are querying the database, may use a number of scope conditions to make restrictions, such as the search for a time period of a certain age group of employees, when it is necessary to accept that MySQL ca

How does mysql optimize insert record speed and mysql optimize insert When a record is inserted, index, Uniqueness check, and the number of records inserted at a time are mainly affected. Based on these conditions, you can optimize the insert record speed. This section describes several methods to optimize the insert

When the data rows in the TABLE are deleted, the occupied disk space is not immediately recycled, after the optimize table command is used, the space will be recycled and the data rows on the d

Use RequireJS to optimize the JavaScript reference code method, and requirejs to optimize RequireJS is an effective way to improve the speed and quality of your javascript code. It also makes your code easier to read and maintain. In this article, I will introduce you to RequireJS and how to use it. We discuss introduction of files and definition modules, and even access to optimization knowledge. To put it

How to optimize the MYSQL database and optimize the mysql database 1. select the most suitable field attribute Minimize the length of the defined field and set the field not null, for example, 'province, gender'. It is best to set it to ENUM. 2. Use JOIN instead of subquery: A. Deleting customers without any orders Elete from customerinfo WHERE customerid NOT in (SELECT customerid FROM orderinfo) B. Extract

Don't optimize it! Let the compiler do it !, Optimize the Compiler We often perform optimization on our own when writing code. In fact, most cases are unnecessary because the compiler is much smarter than you think! The example below demonstrates that, This is a kind of recursive writing. Many veterans will tell you that writing performance is low and loop should be used. Int rfact (int x) { Int rval; If (x

calculation in the loop, example: for ($i =0; $i 9. Reduce compute-intensive operations. Reason: Php language features decided, PHP is written in C language, in the upper level, the implementation of the words must pass C to run, just a link effect. PHP is good at connecting webserver with backend services, UI presentation. So intensive business is best achieved through other languages, otherwise it will become a performance bottleneck. 10. Be sure to use quoted strings for key values. Oth

will take the program as the optimization priority object, so that the memory and CPU can be preferentially placed on the program when running the program, it also increases the running speed of the program. If you do not have any special requirements, do not start the "Auto Update" function on your body. Because some of Microsoft's updated things are not what they need, and they waste a lot of time and hard disk space while downloading Those useless things. In "remote", it is best not to selec

This is a very interesting topic, second only to the "virus" topic. I believe that many Windows users have the hard drive sorting experience. In the eyes of many Windows users, "If a hard disk is used for a long time, fragments may occur, and the speed may slow down. A program is required to organize the hard disk, so do not do other work ", it seems to be a matter of natural meaning. I also watched Norton defrag sort, adjust, and display my hard dis

Label:Parameter sniffing is a function of generating an execution plan based on the parameters passed in when SQL Server creates the execution plan for a stored procedure, in layman's terms, the execution plan is generated based on the first parameter for stored procedure, but stored The execution plan generated by the first parameter of the procedure is not necessarily optimal, and when the execution plan is reused for subsequent arguments, the original execution plan cannot respond efficiently

After you delete a large amount of data in your library, you may find that the data file size does not decrease. This is caused by the fragmentation of the data file after the delete operation. discuz! In the system Number setting interface provides the function of the data table optimization, can remove the data file fragment after the deletion operation, reduces the file size, speeds up the future reading and writing operation. You only have to do the bulk deletion, or periodically (such as ev
