      CPU and System Topology

      Server Description

      An ARM64 compute-optimized instance featuring dedicated physical cores for lightweight microservices and basic database workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c6r.xlarge is an ARM-based compute-optimized instance featuring 4 dedicated physical cores on an Ampere Altra processor running at 2.8 GHz. It is configured with 8.0 GB of system memory, providing a 1:2 vCPU-to-RAM ratio, and operates on the KVM hypervisor with a baseline network bandwidth of 1 Gbps. The instance does not include local storage or GPU accelerators. Performance benchmarks show average capabilities in multi-core CPU stress tests and database operations, but weaker results in cryptographic tasks, memory bandwidth, and single-threaded compression. This instance is qualitatively cost-efficient for dedicated ARM64 processing, making it suitable for lightweight containerized microservices, static web serving, and basic database workloads.

      Workload Profiles

      0.344Score
      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.
