Virtual memory minimum physical memory 1.5-twice times the maximum value is 2-3 times the physical memory. Properly set a large point can speed up the program, but the virtual memory is to read and write on the hard disk, will cause a lot of disk fragmentation, fragmentation will further affect the system performance and stability, and now the computer memory is generally 2G or higher, in fact, the general application can set the virtual memory to 0, Then you run a program that consumes only memory instead of virtual memory on your hard disk. That way your computer will be more stable.

This optimization can improve the performance of the system for large-capacity file transfer, but only for the server users have real meaning. We can create a new DWORD (double-byte value) key value in, named Iopagelocklimit. In general, the data set 8~16MB between the best performance, to remember that this value is calculated in bytes, [4] For example, you want to allocate 10MB, is 10x?1024x 1024, which is 10485760. This optimization also requires that your machine has more than 256M of memory.
