Maximum CPU for direct messaging

Does anyone have an understanding of the capacity of a pubsub+ software broker.

If you use “top -H” on the “dataplane-linux” i see all of these VmrNabCore.

Based on what I see in the output its always using 6 of the VmrNabCores but leaves the other 6 untouched overall.

Are we having capacity concerns possibly if we max out all of the 6 cores.

Let me analyze the question about VmrNabCore utilization with 6 cores used and 6 cores untouched.

From reviewing the provided documentation, I cannot find any direct information about VmrNabCore capacity and core utilization when using 6 cores and leaving 6 cores untouched. The documentation discusses various aspects of broker scaling and resources, but does not specifically address this scenario.

The documentation mentions resource requirements and scaling parameters, but does not provide details about VmrNabCore behavior with specific core allocations. Without having concrete facts about this specific configuration, I cannot make any claims about its capacity or utilization.

I recommend checking the following sources for more information about broker scaling and resource utilization:
