      CPU and System Topology

      Server Description

      A memory-optimized x86_64 server offering balanced multi-core performance and high memory density for database and caching workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.u1-c1m8.8xlarge is an x86_64 memory-optimized server instance featuring 32 dedicated vCPUs from 16 Intel Xeon physical cores running at 2.5 GHz, paired with 256.0 GB of RAM. Operating on a KVM hypervisor, it provides a 10 Gbps baseline network bandwidth but lacks local storage and GPU accelerators. Performance benchmarks indicate a trade-off: single-core capabilities are weak, as shown by stress-ng and Geekbench single-core tests, while multi-core performance, memory bandwidth, and database operations achieve average ratings. This resource density makes the instance qualitatively cost-efficient for memory-intensive, multi-threaded workloads. It is best suited for database operations, Redis caching, static web serving, and moderate multi-threaded processing tasks.

      Workload Profiles

      1.1Score
      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.
