{{ic|vfs_cache_pressure}} is a percentage value that controls the tendency of the kernel to *reclaim* the memory which is used for caching of directory and inode objects. The default value is 100. Increasing this value will increase the rate in which these objects are removed from the RAM cache. Decreasing it will allow these objects to be cached in memory longer, consuming additional RAM over time. Depending on your specific workload, increasing or decreasing this value too far can have significant negative impacts on system performance. Experimentation is needed to find the appropriate balance and the default value is reasonable. In general, it is more common to optimize swappiness before experimenting with vfs_cache_pressure. | {{ic|vfs_cache_pressure}} is a percentage value that controls the tendency of the kernel to *reclaim* the memory which is used for caching of directory and inode objects.
