      CPU and System Topology

      Server Description

      A dedicated eight-vCPU compute-optimized instance designed for balanced web serving, software compilation, and moderate database workloads without local storage.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c6a.2xlarge is a compute-optimized virtual server featuring 8 dedicated vCPUs and 16.0 GB of RAM, powered by an AMD EPYC 7H12 processor running at 2.6 GHz on the x86_64 architecture. Operating under the KVM hypervisor, this instance provides 2.0 GB of memory per core but lacks local storage and GPU acceleration, relying instead on a 2 Gbps baseline network bandwidth. Performance benchmarks position the instance in the average tier for Geekbench multi-core (5025.0) and PassMark CPU (10249.39) tests, though synthetic stress-ng CPU metrics are weak. The 1:2 vCPU-to-RAM ratio makes it a resource-dense option for compute-focused tasks. It is best suited for workloads such as static web serving, software compilation, Redis key-value stores, and moderate database operations that do not require high-speed local NVMe storage.

      Workload Profiles

      0.39Score
      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.
