Hi ,
I have bundled the public NICs and added 2 more monitors ( running on 2 of
the 3 OSD hosts)
This seem to improve things but still I have high latency
Also performance of the SSD pool is worse than HDD which is very confusing
SSDpool is using one Toshiba PX05SMB040Y per server ( for a total
Hi David,
I noticed the public interface of the server I am running the test from is
heavily used so I will bond that one too
I doubt though that this explains the poor performance
Thanks for your advice

It might not be a bad idea for you to forgo the public network on the 1Gb
interfaces and either put every

Disk models, other hardware information including CPU, network config? You
say you're using Luminous, but then say journal on same device. I'm
assuming you mean that you just have the bluestore OSD configured without a
separate WAL or DB partition? Any more specifics you can give will be
helpful
Hi,
I'll appreciate if you can provide some guidance / suggestions regarding
perfomance issues on a test cluster ( 3 x DELL R620, 1 Entreprise SSD, 3 x
600 GB ,Entreprise HDD, 8 cores, 64 GB RAM)
I created 2 pools ( replication factor 2) one with only SSD and the other
with only HDD
