      CPU and System Topology

      Server Description

      A compute-optimized instance featuring twenty-four dedicated cores for balanced multi-threaded workloads and moderate memory requirements without local storage.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c5.6xlarge is a compute-optimized instance utilizing the KVM hypervisor and x86_64 architecture. It features 24 dedicated physical cores powered by an Intel Xeon 8163 processor at 2.5 GHz, paired with 48.0 GB of RAM, resulting in a 2.0 GB per core ratio. The instance lacks local storage and GPUs, but provides a baseline network bandwidth of 8 Gbps. Performance benchmarks indicate a distinct tradeoff: single-core capabilities are weak, falling in the bottom 25 percent, whereas multi-core performance, memory bandwidth, and database operations consistently achieve average tier results. This hardware profile is best suited for parallelized, compute-heavy workloads such as multi-threaded software compilation, ray tracing, static web serving, and moderate database operations where high single-thread throughput is not critical.

      Workload Profiles

      0.907Score
      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.
