## Symptoms

- Changing modes from High Availability to Load Balancing causes the bandwidth speed from the Internet to decrease significantly.

## Cause

SecureXL is not supported in Load Balancing mode. Hence, all traffic is forwarded through the Firewall (F2F path), instead of being divided between it and the acceleration paths (PXL and QXL).
