What does "local NVMe" mean for you? AFAIK in AWS if you have a 2 core VM you're getting ~3% of a single disk worth of IOPS for their attached storage. Technically NVMe. Not generally what people think when a laptop can do 50x more IO. The minipc I mentioned has 4x the core count and... well who knows how much more IO capacity, but it seems like it should be able to trounce both. Obviously an even more interesting comparison would be... a real server. Why is a database company running benchmarks on something comparable to my low-end phone?

Anyway, saying unlimited is absurd. If you think it's more than you need, say how much it is and say that's more than you need. If you have infinite IOPS why not do the benchmark on a dataset that fits in CPU cache?
