Hi,
My environment has 32 core CPU, and 256GB memory. The SSD can get
30k write IOPS when use directIO.
Finally, i figure out the problem, after change the scheduler of SSD to
noop, the
performance improve obviously.
Please forgive me, i don't realize IO scheduler could impact performance so
much
Hello,
Firstly, this is clearly a ceph-users question, don't cross post to
ceph-devel.
