Varnish Software and Intel collaborated to create an optimized CDN reference solution, combining Varnish caching with Intel’s high-performance hardware. Testing on bare-metal and containerized setups with 100GbE and NVMe storage achieved up to 194 Gb/s throughput with low latency, even under HTTPS and varying cache hit rates. NUMA-balanced I/O and efficient resource allocation improved predictability and speed. Designed for video-heavy, latency-sensitive workloads, this solution helps CDN providers meet growing demand for HD/4K streaming, cloud gaming, and immersive media while maximizing performance, scalability, and resilience.
