Test instance

Hey Gunnar! So unfortunately I only found time now to join in on the fun and was trying to replicate the test instance. You said 8 cores and 32GB RAM (Hetzner Cloud CCX33) here https://www.morling.dev/blog/one-billion-row-challenge/ And in the repo readme you said 8 cores of a Hetzner AX161, so which one is it? And are you setting the heap size somewhere or is it controlled by the submission? (I saw the hook for JAVA_OPTS) Also, which disk did you set it up with? SATA/NVME SSD? I think this will be very useful for people who want to keep the fun going :) Thanks!
