vpn tcp-optimization—Fine-tune TCP to decrease round-trip latency and improve throughput for TCP traffic (on vEdge routers only). You can configure TCP optimization in service-side VPNs only (VPNs other than VPN 0 and VPN 512).
Optimizing TCP traffic can be useful for improving the performance of SaaS applications, transcontinental links, and high-latency transport devices such as VSAT satellite communications systems.
By default, TCP optimization is disabled.
To configure TCP optimization for individual traffic flows rather than across a VPN, create a centralized data policy that includes the tcp-opt action.
