      CPU and System Topology

      Server Description

      A memory-optimized virtual server featuring dedicated Intel Xeon processors and high memory density for database and caching workloads.

      Memory OptimizedGeneral Purpose

      The Alibaba Cloud ecs.e3.3xlarge is a memory-optimized instance featuring 16 dedicated vCPUs powered by an Intel Xeon 8163 processor running at 2.5 GHz. Built on x86_64 architecture and managed via the KVM hypervisor, it delivers 128.0 GB of RAM, establishing a high 8.0 GB per core memory density. The instance lacks local storage and GPU accelerators. Performance benchmarks reveal a contrast between weak single-core capabilities and average multi-core performance across Passmark and Geekbench suites. Memory bandwidth is moderate, supporting uncached reads at 86.27 GB/sec. This hardware profile is qualitatively cost-efficient for memory-bound applications that leverage multi-threading rather than raw single-core speed. It is best suited for database operations, Redis caching, and static web serving.

      Workload Profiles

      0.792Score
      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.
