HTTP keep-alive

Reusing one TCP connection for many HTTP requests instead of opening a new one each time. It skips the connection handshake, and for HTTPS the TLS handshake, on every request after the first.

Performance

In Quorum#

Every internal call between Nodes costs a 0.5 ms hop plus a 1 ms TCP handshake. Connection reuse research removes the handshake, so each internal call costs 0.5 ms. A request that crosses several Nodes saves 1 ms per hop.
