【 Weak current College 】 memory parameters optimization settings

Memory is a data transmission channel, more memory, faster transfer of data is so extreme and run faster, if you find yourself big memory computer than some small memory computer running slower do feel, this often is due to registry parameter settings inside is not set correctly causing memory cannot reach its maximum advantage. The following is the author listed and memory to run slow related registry parameter optimization settings.

Open the registry editor, locate the [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\SessionManager\MomoryManagement], in the right pane, modify the following registry key value of the parameter.

1. start a large system cache (LargeSystemCache)

In memory to open up a huge memory space for disk file system read-ahead. When the program is a continuous increase of data requested, Windows automatically by the system cache, so that read-ahead with maximum speed Gets the desired data. Because this system buffering enabled more of physical memory, which makes use of the program can be used to reduce the physical memory. Set its value to 1. In this way, the system cache to increase from 4MB 8MB.

2, increasing CPU performance (SecondLevelDataCache)

CPU processing speed is much larger than the access speed of memory, and memory and much faster than the hard disk. This CPU and memory, memory and disk between a performance bottleneck, the previous "LargeSystemCache" in order to alleviate memory and disk bottlenecks, and the CPU in order to be able to quickly process data from memory gets also sets a buffering mechanism L2Cache (L2 cache). Adjust this value allows Windows to better cope with the CPU utilization of the caching mechanism for greater data pre-fetch hits. Recommended that this be set to 512.

3. disable the pagefile (DisablePagingExecutive)

Set its value to 1 (hex), this will make all programs and data mandatory qualification in physical memory to run, instead of using virtual memory. Obviously, when there is enough physical memory to complete the desired task, doing so will make the system performance is greatly improved. For memory only 64 MB of user, enable it perhaps disaster – system error until the crash frequently.

4, custom input/output buffer size (IOPageLockLimit)

Input/output system is a device to transfer data between the microprocessor and the channel, while expanding its buffer size data transfer will be more smooth. Similarly, the specific set of dimensions depending on the size of physical memory and how to determine the running task, generally speaking, if the memory to the 64MB double-byte key value is set to hex (1MB) 400, 800 (2MB) or 1000 (4MB) 128MB memory can be set is 1000 (4MB), 2000 (8MB) or 4000 (16MB); 256 MB 4000 (16MB) or 8000 (32MB). Of course if you have more memory, can set it to 10000 (64MB) or more. When set to 0, Windows will automatically configure.
