GM ☕ Thought for the day:
Politicians don't make Bitcoin relevant.
Bitcoin makes politicians irrelevant.
Cypherpunks make Bitcoin.
Be a cypherpunk, ignore the politicians.

Have you seen these PCIE SSD cards? 50+ GB/s Transfer speeds…that’s like approaching DRAM speeds. HighPoint Technologies Rocket 1608A PCIe Gen5 x16 to 8-M.2x4 NVMe Switch AIC 
I have wondered what would make interacting with my node faster for wallet stuff and ibd…I can fully sync and make all the indexes in 8.5 hrs off another node on the 10GBE lan, but CPU never seems to get stressed (well, not par=16 of them at least). I can’t imagine my NVME drives on either end are the bottleneck, but I’ve always wondered what is the performance bottleneck running bitcoind.

I hadn't seen that nvme switch, it looks pretty sweet. Will have to keep it in mind for future builds.
Bitcoin IBD is I/O intensive both on the network and with random read/write patterns to disk during verification. If you're sync'ing from another node over 10Gb than the network is not the issue.
Then perhaps it’s an iops issue. In my pea-brain, I was thinking reading/writing was more sequential than random, but relatively few large files is just the end result, not necessarily reflective of the process to get to that point.
