      CPU and System Topology

      Server Description

      A memory-optimized instance featuring a high RAM-to-vCPU ratio for memory-intensive workloads requiring dedicated Intel Xeon processing.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.se1.2xlarge is a memory-optimized instance featuring 8 dedicated vCPUs on an Intel Xeon 8163 processor running at 2.5 GHz, paired with 64.0 GB of RAM. Operating on the KVM hypervisor, this x86_64 instance provides a high memory-to-core ratio of 8.0 GB per vCPU but lacks local storage and GPU accelerators. It delivers a baseline network bandwidth of 2 Gbps. Performance benchmarks indicate modest compute capabilities, with single-core and multi-core CPU metrics generally ranking in the bottom 25%. However, it achieves average throughput in large-block memory bandwidth and Redis SET operations. This instance is qualitatively cost-effective for memory-heavy workloads that do not require intense CPU processing, making it suitable for caching layers, relational databases, and general-purpose enterprise applications requiring a larger memory footprint.

      Workload Profiles

      0.344Score
      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.
