Instana (k3s-pods) CPU and MEMORY reservation(requests) at startup is much too high in relation to the real utilization. Results in high number of CPU/MEM at startup which is not used in running state. (Expensive resources)

We are using the self-hosted Instana Standard edition (k3s). More than once we have problems with messages like too less CPU to startup (pending pods). Several times we added CPU but what we see is that when it is running in production the utilization of CPU does not exceed 15% of all the available CPU because of the count of the configured CPU-request of all the pods is very high configured which is not used at running time. For memory the same but is the utilization a bit higher (35 %). A support request to tune this better and bring requests more in balance with real utilization will decrease the CPU/MEM allocation without decreasing performance. Now there is 85% wasted CPU allocation and 65% MEM.
