Some Volumes Were Slow and We Figured Out Why
- shanemhansen 2y agoI do think this was well written and informative. I have a request (I know I know another entitled non customer). Why not tell me how fast they are supposed to be? I hear "they are so fast it sounds like a brag but no really they are super fast" and I just want to know: how fast? I did 2-3 searches and didn't find an answer. Google publishes instructions for benchmarking via fio. https://cloud.google.com/compute/docs/disks/benchmarking-local-ssd-performance https://cloud.google.com/compute/docs/disks/benchmarking-loc... I understand more than most just how variable these results can be but I've always appreciated that the gcp docs essentially give customers repro steps for confirming performance.
- yjftsjthsd-h 2y agoAlso a non-customer so I could be mistaken... but they allow arbitrary code execution; it wouldn't be hard to just run a container image on fly that uses fio or whatever if you wanted to test it. Although I tend to agree that the hosting provider should publish expected perf numbers too.
- EdSchouten 2y agoI think Linux should go the FreeBSD/macOS route of completely deprecating major/minor numbers. Just treat stat.st_rdev as a fully opaque identifier.
