Comment: Added section about performance analysis, with pointer to qlog and qvis

...

  • Minimizing connection establishment and overall transport latency or applications, starting with HTTP/2;
  • Providing multiplexing without head-of-line blocking;
  • Requiring only changes to path endpoints to enable deployment;
  • Enabling multipath and forward error correction extensions; and
  • Providing always-secure transport, using TLS 1.3 by default.

The combination of QUIC and HTTP/2 with some enhancements should result in a new "HTTP/3" standard.

QUIC Encryption vs. Performance Analysis

QUIC mandates encryption for most information, including traditional "transport-level" fields such as sequence numbers. This complicates some performance analysis approaches. Various tools (e.g. qlog/qvis) and (protocol) mechanisms (such as the "spin" bit) have been suggested to address this.
