Why HN links it
HN readers link this blog's posts on the hidden costs of running Kubernetes control planes (etcd and CRDs) and on Docker performance on bare metal. The comments cite them as background, without judging them.
Summarised by Claude from a sample of 2 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
There's this theory - "CRDs Killed the Free Kubernetes Control Plane" https://caleblloyd.com/software/crds-killed-free-kubernetes-... Basically running etcd in production with reasonable SLA and more than a little bit of data is super hard.

HN discussionI think that CRDs are partially to blame for this. CRDs can tax the API Server and backing data store, without directly mapping to a revenue-generating activity. I’ve noticed a trend where teams spin up new clusters for each application. Since CRDs are installed on the cluster level, it is not possible to namespace resource versions. It is easier for teams to take the cluster-per-application approach as opposed to m…

HN discussionIf you need fast storage resources you may notice a performance hit. Performance for CPU and memory resources seems to be mostly the same as Docker on Linux. https://caleblloyd.com/hardware/docker-performance-bare-meta...

HN discussionI write PHP daily with a team if 6. It's Object Oriented support makes it very developer friendly for medium-sized projects if they are architected well. Using a modern framework like Yii2 makes it just as good as any other modern franework in any other dynamic language (rails, django, entity, etc). Yii2 performance also doubles from PHP5.6 to PHP7 for those interested: https://caleblloyd.com/software/yii2-php-7-per…

on “How Badoo Saved $1M Switching to PHP7”Async/Await is especially important to use in .NET and .NET Core web servers if high concurrency is desired. .NET uses a managed thread pool that will only spawn up to something like 50 threads quickly by default. If it sees that more threads are needed, it will slowly add them. This means that a Synchronous web endpoint (think API call that does not use "Async/Await") will hog an entire thread for the life of the r…
