[ceph-users] RGW Index pool(separated SSD) tuning factor

Hi everyone, I confirmed that write performance has increased too much even if I apply just SSD for the index pool of rgw. I know that ~200 Bytes per object in the index pool is created. When I checked the index pool size, it's around 300 bytes ~ 400 bytes calculated. like me, If it uses index pool applying separated SSD devices, I guess there is the tuning factor like block size to reduce index pool size. Is there the tuning factor or recommendation about separated SSD for the index pool?
