how to defragment

One, memory fragmentation refers to the router memory is divided into many discontinuous blocks. He will result in lower memory utilization, which can cause memory errors and affect the performance of routers. It will also lead to the problem of router packet loss, in fact, not only the memory of the router fragmentation problem, the common hard disk also exists in this problem. If the Microsoft operating system with a defragmentation tool, you can protect users to

and increase the probability of failure. When you burn a large number of small files, it is best to defragment the hard disk where the files are stored, and then copy the files you want to burn, otherwise the chances of reading errors are greatly increased. In addition, we also update the drive and burn programs frequently. Should always be concerned about whether the DVD burner manufacturers have released a new version of the driver, to burn the s

The Gho file has a 724MB, larger, so deleted a C disk about 200MB of the file, expect to mirror after mirroring. Gho file is reduced, the result is ghost after the size unexpectedly still 724MB, excuse me what is the reason? A: The file you deleted may be Windows Exchange file, it is used for virtual memory, originally ghost do not save the contents of this file, so delete and th

1. The network bandwidth used is too low, when using the Internet browser, can not meet the normal web browsing. Recommended to enter the speed of the Web site, the speed of testing such as: http://www.wangsu123.cn/; 2. Clean the computer, defragment the disk, uninstall the infrequently used software, and manually delete the junk files left behind in the C-Disk cleanup. 3. Safe mode, the system to complete the antivirus, the virus will cause an unli

　　1. Keep enough space for hard drive Reason analysis: Because the ghost Win7 system needs to use the hard disk as the virtual memory, this requires the hard disk to keep a certain free space to ensure the normal operation of the program. Solution: In general, the minimum should ensure that more than 100MB of space, otherwise prompted the system resources warning is likely to be too small with the hard disk surplus space. There is too much fragmentation of the hard disk and it is also easy to

. Of course, because we do not use all of these features, so to customize the installation of those useful parts to save C disk space! Then set the virtual memory to D disk (only temporary ^_^) and then use the system's own Disk Defragmenter to clean up the C disk. 2, the use of "micro-Xiao Registry optimization master" such as system modification software to "My Documents", "Internet buffering", Internet History "," Favorites "and so on often have to write, delete the operation of the folder s

Super Rabbit clean up the registry and garbage files. 4, close some Start program, start-run-msconfig---start, in addition to anti-virus software, input method outside the general procedures can be turned off. 5, remove the program software. 6, defragment the disk. Second, optimize your computer 1, optimize the visual effect Right-click My Computer-Properties-advanced, and in the Performance column, click Settings-Visual effects, adjust to best

any program at this time, please be patient for a moment. Click "Settings", there will be a new window, you can set according to the actual situation, you can also choose, when the system starts, automatically run "Wopti memory Collation", which can assist you in memory collation. If you cannot accurately determine, click "Recommend", and Windows Optimizer will make the most appropriate choice for you. Click "Advanced", enter the Quick release advanced option, accordi

game can be installed in F disk, G disk used to store audio and video files. 4, to the C disk again to defragment, and then finish the following second big step after the virtual memory set to the C disk! Second, the virtual memory settings Setting virtual memory to a fixed value is already a universal "truth", and it is quite true, but most people set it to a 2~3 partition outside of C disk, and the value is more than the physical memory. Most pe

free space. 3. The spare capacity of the system disk is not small, but because frequently installs, downloads the software, and repeatedly deletes causes the file fragment too many, also is easy to cause the virtual memory to be insufficient one of the reasons, the virtual memory needs a contiguous space, although the disk spare capacity is big, but does not have the contiguous space, also cannot establish the virtual memory area. You can defragment

In general, the mouse is a pause is the sensitivity of the mouse, the sensitivity of the error is a common optical mouse fault, specific performance for mobile mouse, the cursor unresponsive, do not listen to command. This hardware failure suggestion is to change a new mouse immediately. However, it is best to use the following troubleshooting reasons to verify that the mouse paused in the end is where the problem! First, make sure your mouse is good. You can switch to other computers to try. T

running on this platform. As far as this problem is concerned, the second factor that affects the performance of your database program is disk access. During execution, access to the physical disk is always a bottleneck (compared to accessing the data stored in RAM), so you should minimize access to the disk. However, since your application always has to deal with some disk or some other physical device, your goal should be to ensure that all disk access is as effective as possible. The way to

Understanding the memory storage of memcachedThe memcached is a distributed cache server. This article will introduce the implementation of the internal structure of memcached and how the memory is managed. In addition, weaknesses caused by the internal structure of the memcached will also be explained.Slab allocation mechanism: Defragment memory for reuseThe most recent memcached by default uses a mechanism called slab allocator to allocate and manag

digits that represent the offset from the start of the file for the cell contents in the cell content area. Lattice cell pointer-type orderly. The system tries to ensure that the free space is located after the last cell pointer, which ensures that the new cells can be added quickly without having to rearrange the page (defragment). The cell contents are stored at the end of the page and grow to the beginning of the file. Unused space in the cell c
