A cache memory is used by operating systems to store frequently accessed data. As the cache memory is a part of the RAM, it is faster to access and retrieve information from the cache
memory compared to getting the information or files from the hard disk. In Windows, including Windows 7, it is possible to increase the performance of a disk cache
through a modification of the system registry. Take a backup of the registry before running REGEDIT. Change the values of the LargeSystemCache
key in the registry from 0 to 1. This should increase the performance of a disk cache
What is the disk cache?
The disk cache is used to store disk information in RAM. Access to RAM is faster than the hard disk, so the information will be available more rapidly.
First and foremost, and as with any registry modification, it is advisable to backup the entire contents of the registry, or at least the key(s) you want to edit.
