A security administrator is troubleshooting a performance issue on an R81 Security Gateway. The administrator runs 'fwaccel stats -s' and observes that a large number of connections are being handled by the Firewall path instead of being accelerated. The administrator wants to identify which specific connections are not being accelerated. Which command should be used to view the acceleration status of active connections?

An administrator is tuning a Security Gateway with CoreXL enabled. The administrator notices that the 'fw_worker' processes are evenly distributed across cores, but overall throughput is lower than expected. After checking SecureXL, the administrator finds that a significant portion of traffic is not being accelerated. Which of the following is the most likely cause for this performance bottleneck?

A security administrator is troubleshooting a performance issue on an R81 Security Gateway (156-315.81.20) with SecureXL enabled. The administrator runs 'fwaccel stats' and observes a high number of packets in the 'P' (pass) path but also a significant number in the 'F' (forward) path. Which action should the administrator take to improve performance?

A firewall engineer is troubleshooting a CoreXL-enabled R81.20 gateway where a single firewall instance appears saturated while others are lightly loaded, even though SecureXL is active and the interface is configured for multi-queue. After reviewing fw ctl multik stat output, the engineer suspects that the distribution of connections across instances is uneven. Which factor most directly explains why CoreXL instance distribution can become skewed on this gateway?

An administrator is tuning a Check Point Security Gateway with CoreXL enabled. The administrator observes that the 'fwaccel stat' output shows that SecureXL is enabled, but the 'fwaccel stats' command indicates a high number of packets being handled by the 'PXL' path. Which of the following is the most likely reason for this behavior?

A security administrator notices that a Check Point Security Gateway with SecureXL enabled is still forwarding a portion of traffic through the Firewall Kernel path. The administrator runs 'fwaccel stats -s' and observes a high number of 'Accelerated conns' but also a substantial number of 'Non-accelerated conns'. The administrator wants to identify which traffic is not being accelerated. Which command should be used to view detailed information about non-accelerated connections?

A security administrator is troubleshooting a Security Gateway that shows low throughput despite low CPU utilization. The administrator runs 'fwaccel stats -s' and observes that the 'Accelerated' packet count is extremely low, while 'F2F' (Forward to Firewall) packets are high. The administrator wants to understand why traffic is being sent to the Firewall path instead of being accelerated. Which of the following is the most likely reason for this behavior?
