Subject: using fio tool in ceph development cluster (vstart.sh)

Hi,

I am using the Ceph development cluster through vstart.sh script. I would like to measure/benchmark read and write performance (benchmark ceph at a low level). For that I want to use the fio tool.

Can we use fio on the development cluster? AFAIK, we can..... I have seen the fio option in the CMakeLists.txt of the Ceph source code.

Thanks in advance.
