Shameless plug here, but if anyone wants to benchmark in-memory vs. NVMe NAND SSD vs. NVMe Intel Optane DC SSD performance, we're looking for someone with FoundationDB expertise to give it a shot and share their learnings with the community. Make a request for a server by posting a new issue at our Github page [1].

Basically, I'm curious to know how FDB's memory engine performs compared to the SSD engine with a standard NAND SSD and an Intel Optane DC SSD. Something along the lines of the throughput per core and latency results on the FDB performance page [2].

Disclosure: I'm working at Intel and help manage our open source lab with our friends at Packet.

Only tangentially related, but are there any public Postgres benchmarks for systems running high-CPU, high-memory, p4800x optane drives?

Would something like the TSBS [1] help with this? It's TimescaleDB but they're built on Postgres. They have built-in high-CPU queries, but I haven't seen high-memory before. Can you point me in the right direction? Otherwise, we've had some Postgres people use the lab and are waiting on their decision whether to share publicly.
