Writecache simply doesn't care about caching your reads at all.
Your RAM with it's page caching mechanism keeps read data as long as
there is free RAM for this - the less RAM goes to page cache - less read
operations remains cached.
Hi, does it mean that to have *both* fast write cache *and* read cache
one should use a dm-writeback target + a dm-cache writethrough target
(possibly pointing to different devices)?
Can you quantify/explain why and how faster is dm-writeback for heavy
write workload?
Thanks.
