Constant HANDSHAKE_TIMEOUT

pub const HANDSHAKE_TIMEOUT: Duration;

The timeout for connections and handshakes when connecting to new peers.

Outbound TCP connections must complete within this timeout, then the handshake messages get an additional HANDSHAKE_TIMEOUT to complete. (Inbound TCP accepts can’t have a timeout, because they are handled by the OS.)

This timeout should remain small, because it helps stop slow peers getting into the peer set. This is particularly important for network-constrained nodes, and on testnet.
