HTTP/3 marks a significant advancement in protocol development, utilizing QUIC as its underlying transport layer to exploit multiplexing capabilities and minimize head-of-line blocking. The introduction of the Extensible Prioritization Scheme (EPS) offers a signaling mechanism for controlling the order of resource delivery. In this study, we propose mappings from Chromium priority hints to EPS urgency levels with the goal of enhancing the key web performance metrics. The mappings are evaluated using EPS's urgency-based, non-incremental resource delivery method. The results of the experimental evaluation show that the proposed mappings improve the Quality of Experience metrics across a range of websites.
