      CPU and System Topology

      Server Description

      An arm64 compute-optimized instance delivering dedicated Ampere Altra performance and high multi-threaded efficiency for containerized workloads and web serving.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c6r.8xlarge is an arm64-based compute-optimized instance featuring 32 dedicated vCPUs powered by a 2.8 GHz Ampere Altra processor and 64.0 GB of RAM. Operating on the KVM hypervisor, this instance provides a 1:2 vCPU-to-RAM ratio, 8 Gbps baseline network bandwidth, and no local storage or GPU accelerators. Performance benchmarks show average multi-core capabilities, with a stress-ng multi-core score of 57,239.02 and a strong multi-threaded bzip3 decompression throughput of 217.66 GB/sec. It also handles database operations efficiently, achieving 44.07 million Redis SET operations per second. The arm64 architecture delivers excellent resource density and qualitative cost efficiency for multi-threaded workloads. This server supports web serving, software compilation, containerized applications, and lightweight machine learning inference.

      Workload Profiles

      1.6Score
      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.
