      CPU and System Topology

      Server Description

      An x86 server combining sixty-four dedicated cores with over seven terabytes of local SSD storage for data-intensive multi-threaded workloads.

      Storage & DatabaseGeneral Purpose

      Alibaba Cloud ecs.i2g.16xlarge is an x86_64 server featuring 64 dedicated Intel Xeon 8163 cores running at 2.5 GHz, 256 GB of RAM, and a bundled 7679 GB local SSD. Operating on a KVM hypervisor, it delivers a 10 Gbps baseline network bandwidth. Performance benchmarks reveal a distinct tradeoff: single-core CPU execution is weak, ranking in the bottom 25%, whereas multi-core capabilities and memory bandwidth consistently reach average tiers, with multi-threaded bzip3 decompression scoring in the top 25%. Given its high local storage capacity and balanced 1:4 vCPU-to-RAM ratio, this instance is qualitatively cost-efficient for storage-heavy, multi-threaded workloads. It is best suited for database hosting, static web serving, and general-purpose enterprise applications that require substantial local storage but do not depend on high single-core processing speeds.

      Workload Profiles

      1.54Score
      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.
