      CPU and System Topology

      Server Description

      A dedicated 16-core x86_64 server with 64 GB RAM and bundled local SSD storage for balanced multi-threaded workloads.

      General PurposeStorage & Database

      Alibaba Cloud ecs.i3g.4xlarge is an x86_64 general-purpose server featuring 16 dedicated physical cores on an Intel Xeon 8269CY processor running at 2.5 GHz. It is equipped with 64.0 GB of RAM, a bundled 959 GB local SSD, and a 5 Gbps baseline network bandwidth. Performance benchmarks indicate a distinct tradeoff: single-core CPU execution and single-threaded gzip compression fall into the bottom 25% tier, whereas multi-core CPU performance, memory bandwidth, and database operations consistently rank in the average middle 50% tier. With its balanced 1:4 vCPU-to-RAM ratio and dedicated CPU allocation, this instance is suitable for database hosting, static web serving, and multi-threaded processing workloads that benefit from local SSD storage but do not require high single-threaded compute speeds.

      Workload Profiles

      0.809Score
      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.
