Technical Overview

Engineering breakdown of Configuring HTTP/3 QUIC Header Compression (8489). Bare-metal hardware performance requires isolated kernel parameters, tuned NIC offloads, and precise QUIC stack configuration. This article covers RFC 9204 (QPACK) deployment on Linux 6.x kernels, including dynamic table sizing, header block decoding limits, and congestion control interaction.

Kernel & NIC Tuning

Enable net.core.rmem_max and net.core.wmem_max to 16MB for QUIC buffer pools.
Activate ethtool -K eth0 gro on gso on tso on for segmentation offload.
Set net.ipv4.tcp_fastopen=3 to allow QUIC 0-RTT handshakes.

QPACK Dynamic Table Configuration

The dynamic table size directly impacts compression ratio and memory footprint. Recommended settings for high-throughput bare-metal:

quic_qpack_max_table_capacity = 16384  # 16 KiB
quic_qpack_blocked_streams = 100       # Max blocked streams
quic_qpack_max_header_list_size = 65536 # 64 KiB

Monitor quic_qpack_dynamic_table_size via ss -ti to detect eviction storms.
