Security and Performance Characteristics of QUIC and HTTP/3
Fan Liu, Patrick Crowley · 2023
We focus on the security and performance characteristics of the QUIC protocol, exploring its security qualitatively and its performance quantitatively through experimentation. Performance comparisons between QUIC and traditional TCP-based counterparts were made through experiments under various dimensions. These comparisons were based on measurements of running code on real computing and networking resources within Washington University's Open Network Lab (ONL). The experimental results show that QUIC clients perform as well as or better than TCP clients for single-stream resources with limited bandwidth. However, minimal performance differences exist between QUIC and TCP for multiple streams.
