#Decreasing vfs_cache_pressure causes the kernel to prefer
#to retain dentry and inode caches. When vfs_cache_pressure=0, the kernel will
#never reclaim dentries and inodes due to memory pressure and this can easily
#lead to out-of-memory conditions. Increasing vfs_cache_pressure beyond 100
#causes the kernel to prefer to reclaim dentries and inodes.
#Increasing vfs_cache_pressure significantly beyond 100 may have negative
#performance impact. Reclaim code needs to take various locks to find freeable
#directory and inode objects. With vfs_cache_pressure=1000, it will look for
#ten times more freeable objects than there are.
#As Raspberry Pi has low memory, incresed vfs_cache_pressure a lot so less out of memory.
