[DOCS] Warn about impact of large readahead on search (#88007) (#88079) 
When using LVM or software raid on Linux the kernel, or specific
distribution rules, may use higher ergonomic defaults for the
readahead of resulting block device(s). This can adversely affect
search performance due to high page cache thrashing, in search
heavy scenarios when mmap is involved.

Add a clarification section in the docs raising awareness about this
value and preferring the lower default.
