What method is recommended to improve CPU performance on ProxySG?

Reducing the number of emulated certificates is an effective method to improve CPU performance on the ProxySG. Each emulated certificate that the proxy processes requires CPU resources to handle sessions and manage encryption. When the number of certificates is decreased, the load on the CPU is also reduced, leading to improved performance.

Lowering the certificate count minimizes the cryptographic processing demands and streamlines the handling of secure connections, allowing the ProxySG to allocate more CPU resources to other critical tasks and improve overall processing efficiency. This approach is particularly beneficial in environments with high traffic loads and numerous secure connections, where excessive certificate management could lead to CPU bottlenecks.

In contrast, increasing the number of certificates or their size would further strain the CPU, possibly leading to degraded performance. Therefore, reducing the number of emulated certificates is the preferred strategy for enhancing CPU performance in this context.
