R80.x - Performance Tuning Tip - SecureXL Fast Accelerator (fw ctl fast_accel)

The Fast Acceleration (picture 1 green) feature lets you define trusted connections to allow bypassing deep packet inspection on R80.20 JHF103 and above gateways. This feature significantly improves throughput for these trusted high volume connections and reduces CPU consumption.

The CLI of the gateway can be used to create rules that allow you to bypass the SecureXL PSLXL path to route all connections through the fast path.

Tip 1

Use this function to exclude IP's or networks from deep inspection.

What about VSX support? Is it fully supported in VSX? And how is it enabled in VSX - per VS? Or is it enabled in VS0 and then configured per VS?



yes, it's supported with VSX. You have to enable and define rules for each VS.
