      CPU and System Topology

      Server Description

      A memory-optimized cloud instance providing 64 GB RAM across eight vCPUs, optimized for in-memory key-value stores and memory-heavy workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.se1.2xlarge is a memory-optimized cloud instance configured with 8 vCPUs across 4 physical Intel Xeon 8163 cores at 2.5 GHz and 64.0 GB of RAM. Operating on a KVM hypervisor with x86_64 architecture, it delivers 8.0 GB of memory per vCPU and includes support for AVX-512 and AES instructions. The server features no local SSD storage and provides a 2 Gbps baseline network bandwidth without discrete GPUs. Benchmark evaluations show weak single-core and multi-core CPU metrics, balanced by moderate uncached memory bandwidth of 39.75 GB/sec read and solid Redis throughput of 5.94 million SET operations per second. The hardware trade-off favors high memory density over raw compute speed, positioning this server as a cost-effective solution for memory-intensive workloads, in-memory key-value caching, and database applications that do not demand heavy parallel CPU processing.

      Workload Profiles

      0.34Score
      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.
