      CPU and System Topology

      Server Description

      A storage-dense virtual server featuring dedicated Intel processors, balanced memory, and high-capacity local SSD storage for data-intensive workloads.

      Storage & DatabaseMemory Optimized

      Alibaba Cloud ecs.i3.4xlarge is an x86_64 server configured with a dedicated Intel Xeon 8269CY processor offering 16 physical cores and 16 vCPUs at 2.5 GHz. It features 128.0 GB of RAM and a bundled 3839 GB local SSD, supported by a 6 Gbps baseline network bandwidth. Performance benchmarks place this instance in the average tier for multi-core compute, memory bandwidth, and database operations, though single-core execution speeds are relatively weak. Lacking a GPU, it relies on CPU-based execution, demonstrating average throughput in Redis operations and small-model LLM inference. The high local storage capacity and 1:8 vCPU-to-RAM ratio make this instance qualitatively cost-effective for storage-heavy and memory-intensive applications. It is highly suited for database hosting, web serving, and distributed data store workloads.

      Workload Profiles

      0.806Score
      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.
