Optimizing FortiGate-VM performance

This section describes FortiGate-VM and VMware ESXi performance optimization techniques that can improve your FortiGate-VM performance by optimizing the hardware and the VMware ESXi host environment for FortiGate-VM's network- and CPU-intensive performance requirements.

Additionally, the port4 interface MTU is set to be compatible with the OpenStack 10 environment, which has an MTU of 1446 by default. (In the user_data file, the MTU of port4 is set to 1400.) Using the same MTU setting as the OpenStack 10 environment enables the HA heartbeat interfaces to communicate effectively over the ha-sync network.

See these pages for more information on RedHat OpenStack networks and MTU values:

• MTU for VLAN networks is by default 1496 Bytes in Red Hat OpenStack Platform 10
• Configure MTU Settings
