I haven’t tested hard CPU quotas with Nomad but I suspect the issue mentioned above is due to cgroups/CFS and is also applicable to Kubernetes. See these slides

I haven’t tested hard CPU quotas with Nomad but I suspect the issue mentioned above is due to cgroups/CFS and is also applicable to Kubernetes. See these slides for more details: https://www.slideshare.net/mobile/try_except_/optimizing-kubernetes-resource-requestslimits-for-costefficiency-and-latency-highload https://www.slideshare.net/mobile/try_except_/optimizing-kub...
- Pirate-of-SV 6y agoI recall that there's been some improvements to CFS to fix this since 2018.
- chucky_z 6y agoThere's been a ton of improvements over time. That doesn't make it any less foot-gun-y, unfortunately. I had the exact same problem with Kubernetes (and even just straight up containers), I just want to make sure folks are extremely aware of how big of a footgun it is, and to really, really, really test it well.
