Editor to share with you how to set / 3GB startup switch in Windows, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Windows Server 2003 includes support for startup switches so that you can adjust memory usage and memory address space allocation. Regardless of the amount of physical memory on the system, Windows uses a virtual address space of 4 GB, where 2 GB is allocated to user-mode processes (such as applications) and 2 GB is allocated to kernel-mode processes (such as operating systems and kernel-mode drivers). In systems with physical memory equal to or greater than 1 GB, you can use the above two startup switches to allocate more memory to the application (3 GB) and less memory to the operating system (1 GB). The additional virtual address space helps to reduce the number of memory fragments generated in the virtual address space of the Exchange information storage process.

The / 3GB switch can be used to implement this allocation change. This switch is entered in the boot.ini file of the system and takes effect after reboot.

Note:

The / 3GB switch is supported only in the following operating systems:

Windows 2000 Advanced Server

Windows 2000 Datacenter Server

Windows Server 2003 Standard Edition

Windows Server 2003 Enterprise Edition
