If I run rados load-gen with the following parameters: --num-objects 50 --max-ops 16 --min-object-size 4M --max-object-size 4M --min-op-len 4M --max-op-len 4M --percent 100 --target-throughput 2000 So every object is 4M in size and all the ops are reads of the entire 4M. I would assume this is equivalent to running rados bench rand on that pool if the pool has been previously filled with 50 4M objects. And I am assuming the --max-ops=16 is equivalent to having 16 concurrent threads in rados bench. And I have set the target throughput higher than is possible with my network. But when I run both rados load-gen and rados bench as described, I see that rados bench gets about twice the throughput of rados load-gen. Why would that be? I see there is a --max-backlog parameter, is there some setting of that parameter that would help the throughput? -- Tom Deneau _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
