      CPU and System Topology

      Server Description

      A dedicated compute-optimized instance featuring eight vCPUs and sixteen gigabytes of memory for balanced multi-threaded workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c6.2xlarge is a compute-optimized virtual machine instance featuring 8 dedicated vCPUs and 16.0 GB of RAM, running on an Intel Xeon 8269CY processor at 2.5 GHz. Built on the KVM hypervisor with an x86_64 architecture, this instance provides a 1:2 CPU-to-memory ratio and includes 35 MB of L3 cache, though it lacks local storage and GPU acceleration. Benchmark data shows average multi-core CPU and memory bandwidth performance, alongside average results in software compilation and database operations, while single-core metrics remain in the lower quartile. With a baseline network bandwidth of 2 Gbps, the instance is qualitatively cost-efficient for dedicated compute workloads that do not require massive memory footprints. It is best suited for multi-threaded applications, software compilation, and moderate database or caching tasks.

      Performance

      Workload Profiles

      0.44Score
      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.
