Currently reads always come from the primary OSD in the placement group
rather than a secondary even if the secondary is closer to the client.
In this way, only one OSD will be involved in reading an object, this will
result in a bottleneck if multiple clients needs to access to the same file.
For example, a 3KB CSS file served by a webserver to 400 users, will be
read just from one OSD. 400 users directed to 1 OSD while (in case of
replica 3) other 2 OSDs are available?
Yes. Consistency across the cluster is dependent on this scheme, currently.
