We've enhanced the custom-mode configuration to support optimal use of CPU and memory resources. You can limit the CPU utilization of the Layer 3 data plane by configuring the cpu colocation quota parameter. This configuration allows for sharing of CPUs in deployments where the Layer 3 data plane does not require a dedicated CPU. You can configure the CPU utilization rate in custom mode by using the set vmhost mode custom name layer-3-infrastructure cpu colocation quota quota-value command.
We've also introduced support to pin the emulator to specific physical CPUs.
