Hi! Sometimes ago i'm use bcache for caching random write to ssd.
Also i read about lvm cache and some unsuccessful stories about it performance,
sometimes users don't have any benefits when try to use lvm cache.
So if i use kernel 4.7 - does lvm cache can give me performance boost
when random writing? Does it possible to bypass sequential i/o after
some threshold?
What kernel and lvm versions preferred to use to get maximum
performance in lvm cache?
