Subject: Ceph Bluestore OSD CPU utilization
Date: Tue, 11 Jul 2017 10:34:47 +0000	[thread overview]
Message-ID: <694B98CBCEF42547AE4CD1A693225B5D085533EA@CNMAILEX04.lenovo.com> (raw)

Hi,

I installed Ceph luminous v12.1.0 in 3 nodes cluster with BlueStore and did some fio test.
During test,  I found the each OSD CPU utilization rate was only aroud 30%.
And the performance seems not good to me.
Is  there any configuration to help increase OSD CPU utilization to improve performance?
Change kernel.pid_max? Any BlueStore specific configuration?

Thanks a lot!

B.R.
