- Move TCP_NODELAY to start of transport_handshake to ensure immediate handshake transmission. - Enable TCP_QUICKACK in socket_transport_send to prevent delayed ACKs during event transmission.

@csa7mdm thanks again for your contribution. I shared in #122344 (comment) that we were able to fix the problem on the VS / VSCode side and a fix is being worked through. Since no runtime change is required to make things better, I'm going to close this PR. |
