      CPU and System Topology

      Server Description

      A high-capacity local SSD storage instance with 52 vCPUs, optimized for parallel processing and database workloads.

      Storage & DatabaseGeneral Purpose

      Alibaba Cloud ecs.i3g.13xlarge is an x86_64 server instance powered by a dedicated Intel Xeon 8269CY processor operating at 2.5 GHz. It is configured with 52 vCPUs, 192.0 GB of RAM, and 2879 GB of local SSD storage, running on a KVM hypervisor with a 16 Gbps baseline network speed. Benchmark data reveals a tradeoff: single-core performance is weak, falling into the bottom 25% tier, whereas multi-core performance, memory bandwidth, and database operations consistently achieve average tier results. Qualitatively, the instance offers high resource density, making it cost-efficient for parallelized, storage-intensive workloads. It is best suited for database hosting, static web serving, Redis operations, and multi-threaded data processing tasks that benefit from large local SSD storage but do not require high single-thread compute speeds.

      Workload Profiles

      1.7Score
      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.
