*: <tt>cephx_cluster_require_signatures = false</tt>
*: <tt>cephx_sign_messages = false</tt>
*: (and use <tt>-o nocephx_require_signatures, nocephx_sign_messages </tt> for rbd map and cephfs kernel mounts)
* For good SSDs and NVMes: set min_alloc_size=4096, prefer_deferred_size_ssd=0 (BEFORE deploying OSDs)
* At least until Nautilus: <tt>[global] debug objecter = 0/0</tt> (there is a big client-side slowdown)
* Try to disable rbd cache in the userspace driver (QEMU options cache=none)
* For HDD-only or Bad-SSD-Only and at least until it’s backported — remove the handbrake https://github.com/ceph/ceph/pull/26909
