      CPU and System Topology

      Server Description

      A storage-equipped virtual server featuring dedicated processors and balanced memory for localized database and multi-threaded workloads.

      Storage & DatabaseGeneral Purpose

      Alibaba Cloud ecs.i3g.8xlarge is a storage-focused general-purpose server featuring 32 dedicated vCPUs, 128.0 GB of RAM, and 1919 GB of bundled local SSD storage. Powered by an Intel Xeon 8269CY processor running at 2.5 GHz on a KVM hypervisor, this x86_64 instance delivers a balanced 4.0 GB of memory per core and a baseline network bandwidth of 12 Gbps. Benchmark data indicates a clear tradeoff: single-core performance is weak, ranking in the bottom 25%, while multi-core and memory bandwidth benchmarks consistently achieve average tier results. This hardware profile makes the instance qualitatively cost-effective for storage-heavy workloads that do not require high single-threaded speed. It is well-suited for database operations, caching layers, and general-purpose applications requiring substantial local storage.

      Workload Profiles

      1.3Score
      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.
