fsc Enable local disk caching using FS-Cache (off by default). This

option could be useful to improve performance on a slow link,

heavily loaded server and/or network where reading from the

disk is faster than reading from the server (over the network).

This could also impact scalability positively as the

|
number of calls to the server are reduced. However, local
|
||||||
|
caching is not suitable for all workloads for e.g. read-once

type workloads. So, you need to consider carefully your

workload/scenario before using this option. Currently, local

disk caching is functional for CIFS files opened as read-only.
