[ceph-users] bad performance of leveldb on 0.85

[廖建锋]

Dear,
    is there any body compared the performance with leveldb between 0.80.5 and 
0.85,
  In my pervious cluster(0.80.5),  the average writting speed: 10MB- 15MB
  In current cluster(0.85),  the average writting speed: 5M-8M

what is going on ?   will superblock of leveldb disk cause this ?
