I don’t use Kube, so I’m sorta extrapolating a bit (and I read some PRs into the creator’s repo), but if you watch the video you can see how CPU throttling on Elixir spikes after it hits 100% CPU
This correlates with big spikes in latency on Elixir. We don’t see that happening on Go, since it doesn’t hit 100% CPU.
AFAIK, this is a tuning in Kube issue dealing with CPU quotas. Kube is penalizing Elixir for being at 100% CPU, effectively.
