I don’t disagree but “cores” is not a good measure of computational power.

True, but the cores on a dedicated Hetzner box obliterate the cores on an EC2 machine every time I’ve tested them. So, if anything, it understates the massive performance gap.

  • Hetzner also tends to have more modern SSDs with the latest nvme. Which can make a massive difference for your DB.

    • It's less about the modernity of SSDs and more about a fundamental difference: all persistent storage on AWS is actually networked - it's exposed to you as NVME but it's actually on a SAN and all IO requests go over the network.

      You can get actual direct-attached SSDs on EC2 (and I'd expect performance to be on-par with Hetzner), but those are ephemeral and you lose them on reboot.
