User Experience Evaluation of HTTP/3 in Real-World Deployment Scenarios

QUIC, a standard internet protocol, was developed to perform better in high loss and latency networks. HTTP/3 takes the real benefits of QUIC. In this paper, empirical study of Quality of Experience (QoE) under realistic network scenarios along with the impact of local connectivity, server locations and server software is explored between HTTP/3 and HTTP/2 protocols. To explore the QoE, this paper presents the use of throughput and First Contentful Paint (FCP) metric of the Lighthouse, an open source automated tool by Google to measure the user experience and capture performance of the network protocol. The findings indicate that HTTP/3 performs better than HTTP/2 in more challenging network conditions. The experiments also show that while throughput strongly correlates with FCP for HTTP/2, HTTP/3 throughput is not a good predictor of FCP.
