      CPU and System Topology

      Server Description

      A memory-optimized dual-core virtual server designed for lightweight applications requiring a larger RAM footprint relative to compute capacity.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.e3.medium is an x86_64 virtual server configured with 2 dedicated vCPUs and 16.0 GB of RAM, utilizing an Intel Xeon 8269CY processor clocked at 2.5 GHz. This instance does not include local storage or GPU accelerators. With a memory-to-vCPU ratio of 1:8, it provides a memory-optimized resource profile. However, benchmark data shows limited processing capabilities, with a stress-ng multi-core score of 2162.17 and a Passmark CPU score of 2616.1, both placing in the bottom 10% of tested servers. Memory bandwidth is also constrained, reaching 17.2 GB/sec for uncached large-block reads. Consequently, the ecs.e3.medium is best suited for lightweight, memory-bound workloads, basic caching, or development environments that require a larger memory footprint relative to compute power, rather than high-performance database or web-serving applications.

      Workload Profiles

      0.181Score
      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.
