Dissecting Performance of Production QUIC
Alexander Kwong-Tak Yu, Theophilus Benson · 2021
IETF QUIC, the standardized version of Google’s UDP-based layer-4 network protocol, has seen increasing adoption from large Internet companies for its benefits over TCP. Yet despite its rapid adoption, performance analysis of QUIC in production is scarce. Most existing analyses have only used unoptimized open-source QUIC servers on non-tuned kernels: these analyses are unrepresentative of production deployments which raises the question of whether QUIC actually outperforms TCP in practice.
