I was baffled by this:
"The worst part is that serving the same files from disks local to the VMs is 44x faster than from persistent volumes (267MB/s vs 6MB/s)."
Is it a configuration issue on their side or do the LKE volumes are really limited to 6MB/s on linode?
How can you be happy with this for production??
- gerhardlazu 6y agoBlock 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 ;)
- sweeneyrod 6y agoHey, that speed was good enough in ~1995!
- tracker1 6y agoIt'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.
- gerhardlazu 6y agoFor what it's worth, Rook, OpenEBS or Longhorn are worth exploring.
