CoreXL is supported when which feature is enabled?

CoreXL is a High Availability and Load Sharing feature within Check Point's security architecture. It is designed to enhance performance by enabling the use of multiple CPU cores to handle network traffic more efficiently. Specifically, CoreXL is supported when the IPS (Intrusion Prevention System) feature is enabled because IPS is a resource-intensive process that benefits from the core processing capabilities of CoreXL.

When IPS is active, it can take advantage of the parallel processing offered by CoreXL, allowing the system to inspect packets for threats and vulnerabilities more effectively. This integration ensures that while IPS is managing traffic for security measures, the workload is distributed across multiple CPU cores, thereby improving overall throughput and system performance.

Other features like Route-based VPN, IPv6, and Overlapping NAT do not inherently require or utilize CoreXL to the same degree. While they may operate alongside CoreXL in a full deployment, the specific benefits of leveraging multiple CPU cores are most directly associated with the intensive processing requirements of the IPS feature.
