      CPU and System Topology

      Server Description

      A memory-optimized virtual server featuring twelve dedicated cores and ninety-six gigabytes of RAM for multi-threaded workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.u0.c1m8.3xlarge is a memory-optimized virtual machine instance featuring 12 dedicated Intel Xeon 8163 vCPUs, 96.0 GB of RAM, and a 2 Gbps baseline network bandwidth. Operating on the KVM hypervisor with an x86_64 architecture, this instance does not include local storage or GPU accelerators. Benchmark data reveals a significant performance tradeoff: single-core CPU execution and single-threaded compression speeds are weak, ranking in the bottom 10% to 25%, whereas multi-core CPU performance, memory bandwidth, and database operations consistently fall within the average range. This hardware profile provides a cost-effective option for memory-intensive applications that leverage multi-threaded processing. It is well-suited for database hosting, multi-threaded decompression, and general-purpose workloads that do not require high single-core throughput or local storage.

      Workload Profiles

      0.433Score
      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.
