multiple discrete machines access the file system at the same time. As
long as you use a clustered file system on RBD, you will be OK.
Now, if that performs better than CephFS, is a question you will have
to answer through testing.

Yes you will need to change osd to host as you thought so that copies
will be separated between hosts. You will run into problems you see

at increasing down reporters instead.

Did you see what the effect of just restarting the OSDs before using
tcmalloc? I've noticed that there is usually a good drop for us just
by restarting them. I don't think it is usually this drastic.
