Random read of the same block size can reach 60MB/s with 32 jobs. run fio on ceph-fuse? If I remember right, fio does 1 bytes write. overhead of passing the 1 byte to ceph-fuse is too high. Our ceph cluster consists of 4 OSDs all running on SSD connected through a switch with 9.06 Gbits/sec bandwidth. Any suggestion please?
