Is this really an AWS issue? Sounds like you were just burning CPU cycles, which is not AWS related. WebSockets makes it sound like it was a data transfer or API gateway cost.

I doubt they would have even noticed this outrageous cost if they were running on bare-metal Xeons or Ryzen colo'd servers. You can rent real 44-core Xeon servers for like, $250/month.

So yes, it's an AWS issue.

Hetzner for example. An EPYC 48c (96t) goes for 230 euros

Hetzner network is complete dog. They also sell you machines that are long should be EOL’ed. No serious business should be using them

the hetzner one is a dedicated pcie 4.0 nvme device and wrote at 2.3GB/s (O_DIRECT)

the AWS one is some emulated block device, no idea what it is, other than it's 20x slower
