Hi ALL:
    I've built a ceph0.8 cluster including 2 nodes ,which  contains 5 osds(ssd) 
each , with 100MB/s network . Testing a rbd device with default configuration 
,the result is no ideal.To got better performance ,except the capability of 
random r/w  of  SSD, which should to give a change? 
     
    2 nodes  5 osds(SSD) *2  , 1 mon, 32GB RAM 
    100MB/S network
and now the whole iops is just 500 . Should we change the filestore or journal 
part ? Thanks for any help!
