      CPU and System Topology

      Server Description

      A storage-dense virtual server combining dedicated multi-core Intel processors with substantial local SSD capacity for database and web serving workloads.

      Storage & DatabaseGeneral Purpose

      Alibaba Cloud ecs.i2g.8xlarge is an x86_64 server featuring a dedicated Intel Xeon 8163 processor with 32 vCPUs, 16 physical cores, and 128.0 GB of RAM. It includes a bundled 3839 GB local SSD and provides a baseline network bandwidth of 6 Gbps. Performance benchmarks show weak single-core CPU and memory scores, but average multi-core scaling, memory bandwidth, and database operations. This hardware profile makes the instance highly suitable for storage-intensive workloads, database management, and static web serving where local storage capacity is prioritized over high single-threaded compute speeds.

      Workload Profiles

      0.94Score
      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.
