      Server Description

      A balanced general-purpose platform offering high-core density and average multi-threaded performance for enterprise workloads without local storage.

      General Purpose

      Amazon Web Services m4.16xlarge is a general-purpose instance featuring an Intel Xeon E5-2686 v4 processor with 64 vCPUs, 32 physical cores, and 256.0 GB of RAM. Operating on the Xen hypervisor, this x86_64 platform lacks local storage and GPU accelerators but provides a baseline network bandwidth of 25 Gbps. Benchmark results demonstrate a significant performance divergence: single-core metrics, including single-threaded compression and text processing, rank in the bottom 10%, whereas multi-core benchmarks, memory bandwidth, and Redis operations consistently place in the middle 50%. This hardware profile offers a balanced resource density suitable for multi-threaded workloads, software compilation, and database operations, though it presents a clear tradeoff for single-threaded applications and modern large language model inference.

      Workload Profiles

      1.6Score
      Precomputed compound score for Cache Intensive workloads. A weighted average (geometric mean) of benchmark scores compared to their medians: score = ∏ (x_i / m_i)^(w_i / Σw). The score of 1.0 represents a synthetic baseline server with the median performance of each component benchmark; 0.5 means roughly half the performance; and 2.0 means twice the performance of that reference profile. Component weights: 50% Redis RPS (pipeline=1, SET), 20% Redis RPS (pipeline=16, SET), 10% PassMark Memory Mark (composite), 10% Memory bandwidth (read, 16 MB ~ L3), 10% PassMark single-thread CPU. Rationale for component selection: In-memory key-value store workload, mixing direct Redis performance metrics with memory speed and latency benchmarks, and single-core CPU performance profiles.
