Block storage is an area that we are working with Linode to improve. That's the random read/write performance, as measured by fio.

We have mostly sequential reads & writes (mp3 files) that peak at 50MB/s, then rely on CDN caching (Fastly makes us happy in this respect).

CDN caching is something that we are currently improving, which will make things quicker and more reliable.

The focus is on reality vs the ideal, and the path that we are taking to improving not just changelog.com, but also our sponsors' products. No managed K8S or IaaS is perfect, but we enjoy the Linode partnership & collaboration ;)

Hey, that speed was good enough in ~1995!

It's a relatively common problem... if you need more IO, you may want to try a stripe of 4-8 block storage connections.

Then again, depends on what you're doing.

For what it's worth, Rook, OpenEBS or Longhorn are worth exploring.
