Linux Server Intel QAT for Hardware Crypto Acceleration

In this episode, Lucas and Luna dive into Intel QuickAssist Technology (QAT) for Linux servers—a hardware accelerator that offloads cryptographic operations like TLS handshakes and IPsec encryption from the CPU. They walk through how QAT works at the kernel driver level, how it integrates with OpenSSL via the async engine, and real-world performance gains: up to 50% lower latency for TLS and 4x throughput for symmetric encryption on the same hardware. The hosts discuss when QAT makes sense (high-traffic web servers, VPN gateways, CDN nodes) and its trade-offs: increased power consumption, licensing costs, and the need to pin application memory for DMA. They also touch on alternatives like AES-NI and ARM's Cryptographic Extension. This is a practical guide for sysadmins considering hardware crypto offload to scale without upgrading CPU cores.
