I'm calculating heavy R workloads on ACI in a Docker container (https://hub.docker.com/r/rocker/r-ver Tag 3.5.3). The calculations are working in ACI, but it's slower than expected. When observing the CPU metrics in Azure portal I see that the maximum CPU usage throughout the whole process is at ~1.5 vCPU although I reserved 4 vCPUs.
Is there a tweak to this? I found nothing in the Docker and Azure documentation.
Kind regards
