Go is not cgroup aware. This means the VictoriaMetrics operator will be throttled hard in containerised environments with CPU limits.
The below screenshot shows the container with a CPU limit in Kubernetes. The first half of the time series is on a 13600k, with 20 threads. The second half is when the machine changed to use an EPYC 7763 with 128 threads.
automaxprocs can use cgroups automatically.
