Bug Description
Ceph package has an option to use jemalloc through /etc/default/ceph. It would be nice if ceph-osd charm exposes the option through charm config.
Basically, install libjemalloc1 package, rewrite /etc/default/ceph and restart OSD are requried.
[/etc/default/ceph]
# /etc/default/ceph
#
# Environment file for ceph daemon systemd unit files.
#
# Increase tcmalloc cache size
TCMALLOC_
## use jemalloc instead of tcmalloc
#
# jemalloc is generally faster for small IO workloads and when
# ceph-osd is backed by SSDs. However, memory usage is usually
# higher by 200-300mb.

This bug is dependent on https:/
The ceph-osd is not build with the --with-jemalloc option, so adding the above option to /etc/ceph/default has no effect.
