Hi Sage and Mark,

We had another test case (24 hours filestore run with journal stored in Optane drive) done, under our write intensive workloads, we saw IOPS increased by 59%, average latency reduced by 37%, but tail latency (99.99th) went up 65%. This new result is more meaningful for our production consideration.
Do you have any thoughts on why tail latency went up?

Thanks,
Jianjian

Hi James,

Do you know how many systems were running the RBD clients?

Thanks,
Orlando
