I did find the journal configuration entries and they indeed did help for
this test, thanks
Configuration was:
journal_max_write_entries=100
journal_queue_max_ops=300
journal_queue_max_bytes=33554432
journal_max_write_bytes=10485760
Configuration after update:
journal_max_write_entries=1

I am testing attached volume storage on our openstack cluster which uses
ceph for block storage.
our Ceph nodes have large SSD's for their journals 50+GB for each OSD. I'm
