-config FSCACHE_HISTOGRAM
- bool "Gather latency information on local caching"
- depends on FSCACHE && PROC_FS
- help
- This option causes latency information to be gathered on local
- caching and exported through file:
-
- /proc/fs/fscache/histogram
-
- The generation of this histogram adds a certain amount of overhead to
- execution as there are a number of points at which data is gathered,
- and on a multi-CPU system these may be on cachelines that keep
- bouncing between CPUs. On the other hand, the histogram may be
- useful for debugging purposes. Saying 'N' here is recommended.
