accelerate system running speed

You could take follwing measures to optimize (Winxp)and accelerate system running speed

1.Use anti-virus software to kill virus, ensure system without virus.

2, running a defragment procedures, finishing disk, eliminate disk fragments

 

3. Remove startup item: start - run - msconfig - start, close unnecessary startup item .

4. 4 accelerate the startup and shutdown speed: start registry editor ( Regedit. Exe), find HKEY_CURRENT_USER Control Panel ,change the value of HungAppTimeout to[0], rewrite [WaitToKillAppTimeout] string values of numerical data as [1000]. In the HKEY_LOCAL_MACHINE System CurrentControlSet Control, will HungAppTimeout] [string values of numerical data change for [0], [WaitToKillServiceTimeout] string values of numerical data change as [1].

5. Shut down stop response procedures automatically: start registry editor, find Control Panel HKEY_CURRENT_USER thing, change AutoEndTasks] [string values of numerical data to [20], restart is ok ; Shutdown closed stopped responding programs automatically: find HKEY_USERS < > DEFAULT Control Panel HKEY_CURRENT_USER thing (or Control Panel thing), on the right window will AutoEndTasks] [of numerical data to [1], cancellation or restart.

6, clear unused DLL file: start registry editor, find HKEY_LOCAL_MACHINE Windows Microsoft SOFTWARE CurrentVersion Explorer, create a DWORD value AlwaysUnloadDLL] and [the a value for [1]. Note: if the a value for [0] represents disable this function.

7. Accelerate broadband accessing speed:

 (1) household version: start registry editor, find HKEY_LOCAL_MACHINE SOFTWARE woman Microsoft Windows, create a new name [Psched] in [the item, Psched] rewrite new dwords value NonBestEffortLimit] to [0]beside right window.

（2) commercial version: [begin] - [running] - type [gpedit.msc], open the local computer strategies, select [computer configuration] on the left window  - [management templates] - [network] - [QoS packet scheduler], double-click restrictions may retain the bandwidth of the on the right window ", select "has enabled" and will "bandwidth constraints (%)" set to 0 application - determine, restart is ok.

8, fast sharing and browsing local area network: start registry editor, find HKEY_LOCAL_MACHINE Windows Microsoft Software is RemoteComputer Explorer pages NameSpace, in the next, a {D6277990-4C6A - 11CF - 8D87-00AA0060F5BF} items, to delete it, restart your computer, Windows XP will no longer check predefined tasks, improve the speed obviously.

 

 

 

9.Using CPU L2 Cache to accelerate the overall efficiency: start registry editor, find HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet SessionManager Control MemoryManagement, change dwords value of SecondLevelDataCache] [numerical data ch with CPU L2 Cache for the same decimal numerical on the right window : for example, P4 1.6 G A Cache of L2 512Kb, numerical data for amendment in decimal numerical [512].

　　

10 run Defrag program when start computer

Start registry editor, find HKEY_LOCAL_MACHINE Microsoft SOFTWARE Dfrg BootOptimizeFunction string values, [set for: [Y] is equal to open, [N] is equal to shut down.

　　

11. 11, memory performance optimization

a few options of Windows XP can be optimized to Memory performance, all of them in the registry below position: HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet SessionManager Control with Management.

 

　

(1) the disable Paging memory Paging (our)

Under normal circumstances, XP will take the memory fragments writing drive, can prevent it to do so, let data retention in memory, so as to enhance the performance of the system. Have 256M above memory user just good use this setting. This setting is the name of the Paging our], [Disable its value from [0] to [1] may inhibit memory Paging.

 (2) improve the System buffer: [about the Cache] key value from views on [0] to [1], Windows XP will put in addition to 4M outside of System memory < > http://baike.baidu.com/view/404470.htm all assigned to the file System Cache, it means XP in memory running kernel can greatly improve the System speed. The rest of the 4M disk cache memory is used to do, under certain conditions need, XP will allocate more. Generally speaking, the optimizing the performance of the system get quite ascension, but may also make some application < > http://baike.baidu.com/view/330120.htm degraded performance. Have 256M more memory, just good activation about Cache System.

　12, request row priority for IRQ interrupt: the computer's main components are installed IRQ interrupt. By modifying IRQ request priority can achieve optimization purposes. The main optimization is the object system/CMOS real clock, it through the mainboard to improve performance. Decide to which component higher performance, find the hardware IRQ interrupt. Open the system properties, select the "hardware" TAB, click "device manager < >" button, http://baike.baidu.com/view/493698.htm right-click IRQ number of components to check, select "properties", and click "resource" TAB. Can see equipment use IRQ interrupt. Write down interrupt, running registry editor, launched HKEY_LOCAL_MACHINE System CurrentControlSet PriorityControl, establishing Control called [IRQ# Priority] (" # "is the specific IRQ interrupt) dwords value, and it's a value for [1]. If the system CMOS real clock IRQ interrupt is 8, and build up the value of the IRQ8Priority] [name is. Reboot after, you will find just optimized component performance improved. Strongly suggest using this method to optimize the system CMOS real clock. Also can move multiple IRQ interrupt priority raised, but the effect is not so nice, possibly resulting system instability. Put this optimization design-aside cancel that you have just now established registry keys can be deleted.　

 

13, turn off the debugger Dr. Watson: open book list, to find HKEY_LOCAL_MACHINE SOFTWARE Microsoft Windows NT CurrentVersion AeDebug, Auto] [string values of numerical data to [0], hit F5 refresh make Settings to take effect, they cancel its operation

14 .clos system attributes, which makes speed special-effects splurge. Start - control panel - system - senior - performance - Settings - in visual effect, set to adjust for best performance - sure can. Such desktop would be with win2000 similar, if they like XP blue window, can be in "in the window and button on the use of visual style" hit a tick.

 

15,use Windows commadner + Winrar to manage files, Win XP ZIP support to even without than, for whatever need, boot system will open a ZIP support, original little system resources < > and http://baike.baidu.com/view/53557.htm less a point, and started running, tapping into a "guide-explore-design-grasp regsvr32 / u zipfldr. DLL", then press enter confirm can, success is the sign of the appear a hint window: zipfldr. The DLL success. UnrgisterServer DLL

16, open the DMA: choose IDE ATA/controllers in device manager, to ask/ATAPI Secondary IDE inside any senior set, it's all forwarding mode is set to use the DMA (if applicable), the system will automatically open DMA support (in the BIOS, should also be first set to support DMA).

Whats the BIOS / CMOS interrupt for controlling the CPU's clock speed? Is there one? There has to be,.?
