      CPU and System Topology

      Server Description

      An x86_64 compute-optimized instance with eight dedicated Intel Xeon cores and a balanced two-gigabytes-per-core memory configuration for moderate workloads.

      Compute Optimized

      Alibaba Cloud ecs.c5.2xlarge is an x86_64 compute-optimized server instance featuring 8 dedicated Intel Xeon 8163 CPU cores running at 2.5 GHz and 16.0 GB of system memory. Lacking local storage and GPU accelerators, it relies on a baseline network bandwidth of 2 Gbps. Performance benchmarks indicate modest capabilities, with single-core and multi-core CPU metrics generally falling into the bottom 25%, though large-block memory bandwidth and extended instruction tests achieve average marks. The instance's 1:2 RAM-to-vCPU ratio makes it suitable for dedicated, moderate-intensity compute tasks such as lightweight web serving, basic software compilation, and small-scale containerized applications that do not require high memory density or local storage.

      Workload Profiles

      0.383Score
      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.
