vLLM Architecture, Memory and Benchmarks Deep Dive

vLLM has become essential infrastructure for high-throughput local LLM serving, and this deep dive into its architecture offers practical insights for optimizing deployments. Understanding vLLM's memory management patterns—particularly its PagedAttention mechanism for KV cache optimization—is crucial for practitioners running inference servers locally. The analysis provides concrete benchmarking data that helps inform hardware choices and deployment configurations.

For local deployment scenarios, vLLM's efficiency matters enormously since self-hosted setups often operate on constrained resources compared to cloud infrastructure. This technical breakdown enables practitioners to make informed decisions about batching strategies, GPU memory allocation, and throughput targets, directly impacting whether a local deployment is feasible with available hardware.
