Linux: Clear Memory Cache
The Linux kernel uses unused main memory as a cache to keep page cache, filesystem dentries and inodes. The use of the cache or buffer memory accelerates access to files stored on non volatile storage such as hard disks. The cached items can be cleared from memory by sending a signal to the Linux kernel using the /proc filesystem or the sysctl command.
