Hardware Performance

For optimal performance, deploy dedicated hardware appliances or dedicated resources. Dedicate 4-6 CPU threads, 4GB RAM and Solid State Disk storage.

Network Performance

For optimal performance, connect the LAN/WAN virtual interfaces to physical interfaces that are capable of at least 1 Gbps. Avoid sharing physical network interfaces with other VMs. Where possible assign a physical interface to a single lan0 or wan0 interface.

Virtual Appliance Performance

Where possible try to provision more resources than the absolute minimum. Allow at least two or more CPU threads. Consider assigning at least 6 CPU threads for a high performance MultiSite data center device. Dedicate resources to the virtual appliance where possible. Oversubscription will create a performance bottleneck.

Providing more RAM memory also improves peak performance. Reserve the RAM for the virtual appliance. Load the 64-bit image to access all available RAM. More RAM will also reduces disk IO.

Disk Input/Output per second is critical to performance. Dedicate low latency local storage. Avoid using remote storage like SAN/NAS. It is important to ensure the storage medium will not introduce high IO latency.
