      CPU and System Topology

      Server Description

      A compute-dense, x86_64 server configuration offering 24 dedicated vCPUs with a lean memory footprint for parallelized workloads.

      Compute Optimized

      Alibaba Cloud ecs.ic5.6xlarge is an x86_64 compute-focused server instance featuring 24 dedicated vCPUs powered by Intel Xeon 8163 processors running at 2.5 GHz. It is equipped with 24.0 GB of memory, providing a 1.0 GB per core ratio, and does not include local storage or GPU accelerators. Baseline network bandwidth is rated at 8 Gbps. Benchmark data indicates weak single-core performance, but average multi-core processing capabilities, as demonstrated by its middle-tier stress-ng and Geekbench multi-core scores. This resource profile presents a tradeoff of high compute density against low memory allocation and weak single-threaded execution. It is suited for parallelized workloads with low memory footprints, such as multi-threaded software compilation, static web serving, and database operations.

      Workload Profiles

      0.91Score
      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.
