      Server Description

      A network-optimized general-purpose instance featuring high-speed memory bandwidth and dedicated multi-core processing for distributed workloads.

      General Purpose

      Amazon Web Services m5n.16xlarge is an x86_64 general-purpose instance featuring 64 vCPUs and 256 GB of DDR4 RAM, powered by an Intel Xeon 8259CL processor at 3.1 GHz. Operating on the Nitro hypervisor, it lacks local storage and GPUs but provides a high baseline network bandwidth of 75 Gbps. Benchmark data reveals a clear performance tradeoff: single-core CPU execution and single-threaded compression are weak, scoring in the bottom 25%, whereas large-block memory read and write bandwidths are strong, placing in the top 25%. Multi-core processing, database operations, and web serving throughput perform at average levels. This resource profile makes the instance suitable for network-intensive, parallelized workloads such as distributed databases, Redis deployments, and static web serving, where high network throughput and balanced memory density are prioritized over raw single-threaded CPU speed.

      Workload Profiles

      2.18Score
      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.
