High Performance Encryption (HPE) is an Aviatrix technology that enables 10Gbps and higher IPsec performance between two single Aviatrix Gateway instances or between a single Aviatrix Gateway instance and on-prem Aviatrix appliance.

When a gateway is launched with HPE enabled, the Aviatrix Controller will look for a spare /26 subnet segment to create a new public subnet "-insane" and launch the gateway on this subnet. The instance sizes that support HPE are c5 series and m5 series.
