 The command fw ctl pstat can be used to verify the number of active concurrent connections on a gateway. This command displays various statistics about the firewall kernel, such as memory usage, CPU utilization, packet rates, and connection table information. The output of this command includes a line that shows the current number of connections and the peak number of connections since the last reboot. For example:

This means that there are currently 1234 active connections out of a maximum of 8192 connections, which is 15% of the connection table capacity. The peak number of connections since the last reboot was 2345. 

 Dynamic Dispatcher is a feature that optimizes the performance of Security Gateways with multiple CPU cores by dynamically allocating traffic to different cores based on their load and priority. Firewall Priority Queues is a feature that prioritizes traffic based on its type and importance by assigning it to different queues with different weights and limits. To fully enable Dynamic Dispatcher with Firewall Priority Queues on a Security Gateway, you need to run the following command in Expert mode then reboot:

This command sets the multi-core mode to 9, which means that Dynamic Dispatcher is enabled with Firewall Priority Queues. The other commands are not valid or do not enable both features. References: R81 Performance Tuning Administration Guide

The least amount of CPU cores required to enable CoreXL is 2. CoreXL is a technology that improves the performance of Security Gateways by using multiple CPU cores to process traffic in parallel. CoreXL requires at least two CPU cores, one for SND (Secure Network Distributor) and one for a Firewall instance. The other options are either too few or too many CPU cores for enabling CoreXL.
