Recently expressvpn introduced a new feature in their lightway protocol clled light way Turbo:
it basically creates multiple simultaneous tunnels to a vpn server to boost speed. like idm etc.here is what their PR reads:
"Lightway Turbo works by creating multiple tunnels to our servers, each taking traffic to and from your computer. In doing so, we engage multiple cores for processing and can create multiple instances on multiple servers for faster throughput and increased security. In order to make Turbo feasible, we implemented a few key upgrades to Lightway on our Windows app. Firstly, we implemented custom network driver interface specification (NDIS) drivers to enable kernel bypass; this means we don’t have to copy data out of the kernel to handle it, reducing overhead while boosting performance and efficiency."
