Performance dégradation after upgrade to hammer

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi All,

I've just upgraded Ceph cluster from Firefly 0.80.8 (Redhat Ceph 1.2.3) to Hammer (Redhat Ceph 1.3) - Usage : radosgw with Apache 2.4.19 on MPM prefork mode
I'm experiencing huge write performance degradation just after upgrade (Cosbench).

Do you already run performance tests between Hammer and Firefly ?

No problem with read performance that was amazing
