===========
Put up a warning in documentation and recommendation that data inconsistency can be observed if multiple clients access same data when perf xlators like below are enabled
performance.write-behind 
performance.stat-prefetch
 
Above such perf xlators help in improving performance, but has to be enabled based on the workload.
Customer must be aware that if such options are enabled, it is advised that same file is not accessed by multiple client simultaneously. Such workloads should be avoided or perf xlators must be turned off

Refer BZ#1813327 as an example

That also means, this should be highlighted in SMB section as SMB enabled above such options
