We have run benchmarks on our environment (CNPG, Openshift and CEPH in Dutch gov) and compared to Azure Postgres and (CNPG on) Azure AKS.
Pgbench and pg_tps_optimizer.
CEPH indeed is a 'high bandwidth / high latency' storage solution,
and as such we could get to comparable TPS but required more clients.
With 2 vCPU the max TPS was about 17k/18k with AKS and also with OpenShift.
But with AKS we required 34 parallel clients and with OpenShift/CEPH we required 233 clients. More clients <=> more in parallel <=> more TPS on CEPH...
If you are interested I can share some graphs. |
