Hi Mark
Thanks your reply!
Yes, 33T OSD we are use 1 disk per OSD.
- Do you use SSDs for journals? Ask: don't use SSDs for journals , how
much performance can be improved if use SSDs to storage journals?
- What CPU do you have in each node? Ask: CPU : Intel(R) Xeon

You will see roughly twice the throughput unless you are using btrfs
(still improved but not as dramatic). You will also see lower latency
because the disk head doesn't have to seek back and forth between
journal and data par
