Pro-tip: if at all possible do not run this on top of Ceph. Bare metal SSDs or VMs with SSDs.

- SEJeff 7y agoFrom experience I take it? Was Ceph running on any of those?
- gigatexal 7y agoYes it is how we run it in production and sadly it’s not great. On my own laptop I’ve found it to be maybe 85% or so as quick as normal single mode Postgres. That said things aren’t great when the storage layer is doing consensus and replication and then the database is as well.
- manigandham 7y agoThat's normal advice for any database or system that does it's own data replication. Having multiple distributed storage layers never works out well.
