Could you also give the params for the successful runs?
Scale 25, clients 90 and 64, scale 5 clients 90, 64 and 8 (i.e the

Can you say anything about hardware? (My experience is that older,

It's running in a openstack cloud (so is a libvirt guest): 4 cpus, 4 GB
ram and 2 disks: one for each Postgres instance, both formatted xfs. Hmm
so maybe I should run a VM on my workstation and crank the IOPS limit
way down...in the meantime I'll just let it run :-)
