This option enables support for network filesystems, including

helpers for high-level buffered I/O, abstracting out read
|

segmentation, local caching and transparent huge page support.

help
|
|
This option causes statistical information to be gathered on local
|
|
caching and exported through file:
|
|
|
|
/proc/fs/fscache/stats
|
|
|
|
The gathering of statistics adds a certain amount of overhead to
|
|
execution as there are a quite a few stats gathered, and on a
|
|
multi-CPU system these may be on cachelines that keep bouncing
|
|
between CPUs. On the other hand, the stats are very useful for
|
|
debugging purposes. Saying 'Y' here is recommended.
