Description
osd bench is supposed to take a second argument as the block size in bytes, but the default block size of 4MB is always used:
$ ceph tell osd.* bench 102400 4096 { "bytes_written": 102400, "blocksize": 4194304, "bytes_per_sec": "1133884.000000"}
This can be quite useful for detecting slow OSDs, and it's best to see which OSDs are slow on particular workloads, not just 4MB writes.
